In demanding industrial systems, the reliability of the actuator can be just as important as the valve body itself. Water ingress, unexpected power failure, slow emergency response and hazardous operating environments can all affect whether an electrically operated valve performs correctly when it is actually needed.<\/p>\n<p>This is why Fleyenda focuses on more than basic open-and-close automation. Our motorised valve solutions are designed around practical industrial operating conditions, particularly for water treatment, pumping equipment, metallurgy, oil and gas, process skids and other applications where environmental protection, operational reliability and response speed matter.<\/p>\n<p>Four features are particularly important: an available IP68 protection level, a power-failure reset function, selectable 3\u201310 second opening and closing times, and explosion-proof configurations designed for demanding hazardous-area applications.<\/p>\n<div class=\"technical-note\">\n<p>These features are not simply additional specifications on a data sheet. They address four common problems in industrial valve automation: moisture ingress, loss of electrical power, insufficient operating speed and hazardous operating environments.<\/p>\n<\/div>\n<h2>What Is a Fleyenda Motorised Valve?<\/h2>\n<p>A Fleyenda motorised valve combines an industrial valve with an electrically driven actuator to provide automatic or remote valve operation. Depending on the valve configuration, the actuator can be mounted on ball valves, butterfly valves and other quarter-turn industrial valves.<\/p>\n<p>When the control system sends an electrical command, the motor inside the actuator produces rotational movement through a gearbox.

Power-Failure Reset Function<\/h2>\n<p>A conventional electric actuator normally depends on its electrical supply to move the valve. If power disappears while the valve is operating, many standard actuators simply stop and remain in their current position.<\/p>\n<p>That behavior can be acceptable for some applications, but it is not suitable for every process. Certain systems require the valve to return to a defined position when electrical power is lost.<\/p>\n<p>Fleyenda offers motorised valve configurations with a power-failure reset function.

This can be particularly useful for pump equipment, water systems, process isolation and industrial automation where the final valve position during a power failure matters to overall system operation.<\/p>\n<h3>Why Is Power-Failure Response Important?<\/h3>\n<p>Consider an automated pumping system. If electrical power is unexpectedly interrupted, the pump, valve and other equipment may stop at the same time. If the process requires a particular valve to close or return to a defined position, a conventional actuator that simply stops may not provide the desired system response.<\/p>\n<p>A similar issue can occur in tank transfer systems, bypass lines, dosing systems and automated process skids.

Selectable 3\u201310 Second Opening and Closing Time<\/h2>\n<p>Motorised valve speed is often overlooked during procurement. Buyers may focus on valve diameter, pressure rating and actuator torque while treating opening and closing time as a secondary specification.<\/p>\n<p>In reality, operating speed can directly affect process performance. A valve that moves too slowly may delay equipment sequencing, while a valve that moves too quickly can create undesirable hydraulic effects in liquid systems.<\/p>\n<p>Fleyenda motorised valve solutions can provide selectable opening and closing times within approximately 3 to 10 seconds, depending on the selected configuration.<\/p>\n<p>This gives engineers greater flexibility to match valve response to the actual application instead of accepting one fixed actuator speed for every system.<\/p>\n<h3>When Is a 3-Second Motorised Valve Useful?<\/h3>\n<p>Faster actuation can be valuable in automated process equipment where the valve must respond quickly to a control command. Process skids, emergency switching systems and certain oil and gas applications may require relatively short valve operating times.<\/p>\n<p>A fast-acting motorised valve can also reduce waiting time in repetitive operating sequences where the valve cycles frequently as part of equipment operation.<\/p>\n<h3>When Is a Slower Operating Time Better?<\/h3>\n<p>Faster is not always better. In water pipelines and pump systems, rapid closure can cause a sudden change in fluid velocity. Under certain conditions, this can contribute to hydraulic pressure surge or water hammer.<\/p>\n<p>A longer operating time may therefore be preferable for some water-treatment or pump applications. Selecting between different operating speeds allows the actuator response to be coordinated with pipeline length, flow velocity, pump operation and overall system behavior.<\/p>\n<p>This is why adjustable or selectable actuator speed can provide a practical engineering advantage compared with treating valve operating time as a fixed parameter.<\/p>\n<h2><img decoding=\"async\" class=\"alignnone size-large wp-image-11538\" src=\"https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-3-1024x683.webp\" alt=\"\" width=\"780\" height=\"520\" srcset=\"https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-3-1024x683.webp 1024w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-3-300x200.webp 300w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-3-18x12.webp 18w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-3.webp 1536w\" sizes=\"(max-width: 780px) 100vw, 780px\" \/><\/h2>\n<h2>4. Explosion-Proof Performance for Hazardous Areas<\/h2>\n<p>Industrial valves used in oil and gas, petrochemical and certain process applications may operate in areas where flammable gases or vapors can be present. In these environments, electrical actuator selection must consider more than weather protection.<\/p>\n<p>Fleyenda offers explosion-proof motorised valve configurations intended for demanding hazardous-area applications, with options corresponding to markings such as Ex d IIB T4 Gb, Ex d IIC T4 Gb and Ex d IIC T6 Gb, depending on the selected actuator model and certification.<\/p>\n<p>The purpose of a flameproof enclosure is to contain an internal ignition event and prevent it from propagating into the surrounding hazardous atmosphere through the enclosure construction.<\/p>\n<p>This capability makes explosion-proof motorised valves particularly relevant for oil and gas facilities, tank farms, process plants, chemical facilities and other locations where electrical equipment must satisfy hazardous-area requirements.<\/p>\n<h3>Why IIC Capability Is Important<\/h3>\n<p>Hazardous gas groups are not all treated equally. More demanding classifications can require equipment designed for more severe ignition characteristics.<\/p>\n<p>For projects where an IIC-rated actuator is required, choosing an appropriate explosion-proof motorised valve provides greater flexibility than using an actuator intended only for less demanding general industrial environments.<\/p>\n<h3>T4 and T6 Temperature Classes<\/h3>\n<p>Temperature class relates to the maximum surface-temperature requirements applicable to equipment used in explosive gas atmospheres.<\/p>\n<p>Different projects can specify different temperature-class requirements. Fleyenda configurations with T4 and T6 options allow the motorised valve package to be matched more closely to project and hazardous-area specifications.<\/p>\n<div class=\"warning-note\">\n<p>The exact explosion-protection marking must always be confirmed from the certification and nameplate of the selected actuator model. Project area classification, gas group, temperature class and equipment protection level should be checked before ordering.<\/p>\n<\/div>\n<h2><img decoding=\"async\" class=\"alignnone size-large wp-image-11539\" src=\"https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-2-1024x768.webp\" alt=\"\" width=\"780\" height=\"585\" srcset=\"https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-2-1024x768.webp 1024w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-2-300x225.webp 300w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-2-16x12.webp 16w, https:\/\/www.fleyendavalve.com\/wp-content\/uploads\/2026\/08\/motorised-valve-feature-2.webp 1448w\" sizes=\"(max-width: 780px) 100vw, 780px\" \/><\/h2>\n<h2>Why These Four Features Matter Together<\/h2>\n<p>Each of these four features solves a different industrial problem, but their real value becomes clearer when they are considered together.<\/p>\n<p>IP68 protection addresses environmental exposure. Power-failure reset addresses unexpected loss of electrical supply. Selectable 3\u201310 second operation addresses process response and sequencing. Explosion-proof construction addresses hazardous operating environments.<\/p>\n<p>A conventional electric actuator may perform perfectly in a dry indoor utility room but may not be the correct choice for an outdoor pump station or hazardous oil and gas facility.<\/p>\n<p>The advantage of a configurable Fleyenda motorised valve is that the actuator package can be selected according to the actual operating environment instead of treating every automated valve as the same product.<\/p>\n<h2>Fleyenda Motorised Valves for Water Treatment<\/h2>\n<p>Water-treatment plants use motorised valves for raw-water intake, filtration, backwash, chemical dosing, treated-water transfer, tank isolation and distribution.<\/p>\n<p>These installations frequently expose electrical actuators to outdoor weather, high humidity and water spray. For this reason, enclosure protection can be particularly important.<\/p>\n<p>An IP68 motorised valve can provide an appropriate option where the actuator needs enhanced resistance to water ingress.<\/p>\n<p>Valve operating speed should also be selected carefully. Large water pipelines can be sensitive to rapid changes in flow velocity, so the ability to select a suitable closing time can help engineers coordinate the valve with the hydraulic system.<\/p>\n<h2>Fleyenda Motorised Valves for Pump Systems<\/h2>\n<p>Pump equipment is another important application for electric motorised valves. Automated valves can be installed on pump suction lines, discharge lines, bypasses, recirculation lines and skid-mounted process piping.<\/p>\n<p>The valve can be connected directly to a PLC or control cabinet and integrated into the pump startup and shutdown sequence.<\/p>\n<p>Selectable 3\u201310 second operating time allows the valve response to be matched more closely with pump operation. Depending on the system, engineers may require faster switching or a more controlled opening and closing sequence.<\/p>\n<p>Power-failure reset can also be valuable in pump systems where loss of electrical supply should result in a defined valve position.<\/p>\n<h2>Fleyenda Motorised Valves for Oil and Gas<\/h2>\n<p>Oil and gas installations place demanding requirements on both valves and electric actuators. Equipment may be installed outdoors, remotely and in hazardous areas.<\/p>\n<p>In these conditions, an explosion proof motorised valve may be required together with suitable ingress protection, position feedback and defined operating time.<\/p>\n<p>Fleyenda&#8217;s available explosion-proof configurations make the motorised valve suitable for consideration in pipeline stations, tank farms, process systems, utility lines and other oil and gas applications where hazardous-area electrical protection is required.<\/p>\n<p>The exact actuator certification should always be matched to the project area classification before procurement.<\/p>\n<h2>Fleyenda Motorised Valves for Metallurgy<\/h2>\n<p>Steel and metallurgical plants commonly use electric valves in cooling-water systems, process-water networks, pump equipment, utility lines and gas-handling systems.<\/p>\n<p>These industrial environments may expose equipment to dust, water, temperature variation and demanding operating conditions.<\/p>\n<p>Higher ingress protection can improve actuator suitability for harsh locations, while fast or selectable opening times can support automated process sequencing.<\/p>\n<p>Where flammable gases are present in classified areas, the appropriate explosion-proof configuration should also be selected according to the plant specification.<\/p>\n<h2>How to Select the Right Fleyenda Motorised Valve<\/h2>\n<p>Selecting the correct motorised valve should begin with the process rather than the actuator model.<\/p>\n<p>First determine the required valve type, nominal size, pressure rating, process medium, operating temperature and maximum differential pressure. These parameters determine the basic valve construction and required actuator torque.<\/p>\n<p>The installation environment should then be evaluated. If the actuator will operate outdoors, in a wet location or near water-handling equipment, the required enclosure protection should be defined.<\/p>\n<p>Next determine what should happen when power is lost. If the valve must move to a predefined position, the power-failure reset function should be included in the specification.<\/p>\n<p>The required opening and closing time should also be selected according to process requirements. Faster operation may be useful for sequencing, while slower operation may be preferable in surge-sensitive liquid systems.<\/p>\n<p>Finally, hazardous-area requirements should be defined clearly. If explosion-proof construction is required, the project gas group, temperature class and equipment protection level must match the selected actuator certification.<\/p>\n<h2>Motorised Valve Selection Table<\/h2>\n<div class=\"table-wrap\">\n<table>\n<thead>\n<tr>\n<th>Selection Item<\/th>\n<th>What to Define<\/th>\n<th>Fleyenda Option<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Valve Type<\/td>\n<td>Ball valve, butterfly valve or other required design<\/td>\n<td>Matched valve-actuator package<\/td>\n<\/tr>\n<tr>\n<td>Valve Size<\/td>\n<td>Nominal pipeline size<\/td>\n<td>Actuator sized according to valve torque<\/td>\n<\/tr>\n<tr>\n<td>Process Medium<\/td>\n<td>Water, oil, gas or other fluid<\/td>\n<td>Compatible valve materials available<\/td>\n<\/tr>\n<tr>\n<td>Environmental Protection<\/td>\n<td>Indoor, outdoor, wet or exposed location<\/td>\n<td>Up to IP68 configuration<\/td>\n<\/tr>\n<tr>\n<td>Power Failure Behavior<\/td>\n<td>Required position after loss of power<\/td>\n<td>Power-failure reset option<\/td>\n<\/tr>\n<tr>\n<td>Operating Time<\/td>\n<td>Required opening and closing speed<\/td>\n<td>3\u201310 second options<\/td>\n<\/tr>\n<tr>\n<td>Hazardous Area<\/td>\n<td>Gas group and temperature class<\/td>\n<td>Explosion-proof configurations available<\/td>\n<\/tr>\n<tr>\n<td>Control Mode<\/td>\n<td>On-off or other required operation<\/td>\n<td>Configured according to application<\/td>\n<\/tr>\n<tr>\n<td>Power Supply<\/td>\n<td>Required electrical supply<\/td>\n<td>Selected according to project requirements<\/td>\n<\/tr>\n<tr>\n<td>Feedback<\/td>\n<td>Valve position monitoring requirement<\/td>\n<td>Configured according to control system<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>What Information Should Be Included in an RFQ?<\/h2>\n<p>A professional motorised valve quotation should include enough technical information for the supplier to select both the valve and actuator correctly.<\/p>\n<p>Buyers should provide valve type, size, process medium, pressure, temperature, differential pressure, body material, seat material and end connection.<\/p>\n<p>The actuator specification should include power supply, required IP rating, opening and closing time, power-failure behavior, control mode, position feedback and installation environment.<\/p>\n<p>If the valve will be installed in a hazardous area, the required explosion-protection classification should be provided at the quotation stage rather than added after the actuator has already been selected.<\/p>\n<div class=\"technical-note\">\n<p>The most reliable approach is to purchase the valve, actuator, mounting components and required controls as one assembled package.

In demanding industrial systems, the reliability of the actuator can be just as important as the valve body itself. Water ingress, unexpected power failure, slow emergency response and hazardous operating environments can all affect whether an electrically operated valve performs correctly when it is actually needed. This is why Fleyenda focuses on more than basic open-and-close automation. Our motorised valve solutions are designed around practical industrial operating conditions, particularly for water treatment, pumping equipment, metallurgy, oil and gas, process skids and other applications where environmental protection, operational reliability and response speed matter. Four features are particularly important: an available IP68 protection level, a power-failure reset function, selectable 3\u201310 second opening and closing times, and explosion-proof configurations designed for demanding hazardous-area applications. These features are not simply additional specifications on a data sheet. They address four common problems in industrial valve automation: moisture ingress, loss of electrical power, insufficient operating speed and hazardous operating environments. What Is a Fleyenda Motorised Valve? A Fleyenda motorised valve combines an industrial valve with an electrically driven actuator to provide automatic or remote valve operation. Depending on the valve configuration, the actuator can be mounted on ball valves, butterfly valves and other quarter-turn industrial valves. When the control system sends an electrical command, the motor inside the actuator produces rotational movement through a gearbox. This movement is transferred to the valve stem, rotating the closure element between the required positions. The basic principle is similar to many electric actuated valves on the market. The difference becomes more important when the actuator is exposed to water, outdoor installation, emergency power loss, rapid process sequencing or potentially explosive atmospheres. For these environments, simply specifying an \u201celectric actuator\u201d is not enough. The complete motorised valve package should be selected according to the actual operating conditions. 4 Features That Make Fleyenda Motorised Valves Different Feature Fleyenda Capability Main Benefit Ingress Protection Available up to IP68 Improved protection in wet, outdoor and demanding environments Power Failure Function Power-failure reset available Allows the valve to move to a predefined position when normal power is lost Operating Speed 3\u201310 second opening\/closing options Allows valve response time to match process requirements Explosion Protection Ex d IIB \/ IIC T4 \/ T6 Gb configurations Supports demanding hazardous-area applications 1. IP68 Protection for Demanding Industrial Environments Environmental protection is one of the most important considerations when selecting a motorised valve. Electric actuators contain motors, gears, wiring terminals, control boards, switches and other electrical components. If moisture or dust enters the enclosure, the actuator may experience corrosion, electrical faults or eventual failure. Many industrial electric valve actuators are commonly supplied with an IP67 enclosure rating. This level can be suitable for many outdoor and industrial applications, but some projects require a higher level of protection. Fleyenda motorised valve configurations can be specified with protection up to IP68, providing an additional option for applications where resistance to water ingress is particularly important. This can be valuable in water-treatment plants, outdoor pumping stations, equipment skids, washdown areas and other installations where the actuator may operate in a consistently wet or exposed environment. Why Does IP68 Matter for a Motorised Valve? A valve body itself can often tolerate water exposure without affecting operation, particularly when stainless steel or suitable coated materials are used. The electric actuator is different because its enclosure protects electrical and mechanical components. In an outdoor installation, rainwater, condensation, humidity and accidental spray can all challenge enclosure sealing over time. In pumping and water-treatment facilities, valves may also be installed close to tanks, filters or water-handling equipment. Choosing an IP68 motorised valve can therefore provide an additional level of protection for demanding environments compared with a standard actuator configuration. IP rating should always be matched to the actual installation environment. The required mounting position, cable glands, electrical connections and installation procedures should also maintain the specified enclosure protection. 2. Power-Failure Reset Function A conventional electric actuator normally depends on its electrical supply to move the valve. If power disappears while the valve is operating, many standard actuators simply stop and remain in their current position. That behavior can be acceptable for some applications, but it is not suitable for every process. Certain systems require the valve to return to a defined position when electrical power is lost. Fleyenda offers motorised valve configurations with a power-failure reset function. This allows the valve package to respond to loss of normal electrical power rather than simply remaining wherever it happened to stop. Depending on the project configuration, the valve can be designed around the required safe-state philosophy. This can be particularly useful for pump equipment, water systems, process isolation and industrial automation where the final valve position during a power failure matters to overall system operation. Why Is Power-Failure Response Important? Consider an automated pumping system. If electrical power is unexpectedly interrupted, the pump, valve and other equipment may stop at the same time. If the process requires a particular valve to close or return to a defined position, a conventional actuator that simply stops may not provide the desired system response. A similar issue can occur in tank transfer systems, bypass lines, dosing systems and automated process skids. The valve&#8217;s position after power loss can influence reverse flow, drainage, isolation or restart conditions. For this reason, a fail-safe motorised valve or power-failure reset arrangement should be selected according to the operating philosophy of the complete system rather than considered only as an actuator accessory. The required power-loss position should be defined during valve selection. Different applications may require fail closed, fail open or another predefined position, so the correct function should be confirmed before manufacturing. 3.
