Depending on the\r\n          application, the signal can be simple open\/close control or a modulating signal\r\n          such as 4\u201320mA or 0\u201310V.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"mov-working-card\">\r\n        <div class=\"mov-working-number\">02<\/div>\r\n        <h3>Actuator Motor Starts<\/h3>\r\n        <p>\r\n          After receiving the signal, the electric actuator motor begins to rotate. The motor\r\n          drives a gear mechanism that increases torque and controls the movement speed of\r\n          the valve stem or shaft.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"mov-working-card\">\r\n        <div class=\"mov-working-number\">03<\/div>\r\n        <h3>Valve Stem or Shaft Moves<\/h3>\r\n        <p>\r\n          The actuator transfers torque to the valve stem or shaft. For rotary valves such as\r\n          ball valves and butterfly valves, the shaft turns 90 degrees. For linear valves such\r\n          as gate or globe valves, the stem moves up and down.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"mov-working-card\">\r\n        <div class=\"mov-working-number\">04<\/div>\r\n        <h3>Flow Is Controlled<\/h3>\r\n        <p>\r\n          As the valve disc, ball, gate, or plug changes position, the flow path is opened,\r\n          closed, or partially adjusted. This allows the system to control liquid, gas, or steam\r\n          flow without manual operation.\r\n        <\/p>\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"mov-actuator-box\">\r\n      <div class=\"mov-actuator-content\">\r\n        <span class=\"mov-actuator-label\">\u042d\u043b\u0435\u043a\u0442\u0440\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043f\u0440\u0438\u0432\u043e\u0434<\/span>\r\n        <h3>The Role of the Electric Actuator<\/h3>\r\n        <p>\r\n          The electric actuator is the key component of a motor-operated valve.

Valve Automation Basics What Are Motor-Operated Valves? Motor-operated valves are valves equipped with an electric motor actuator that automatically opens, closes, or regulates the flow of liquids, gases, or steam in a pipeline system. Compared with manually operated valves, motor-operated valves allow remote control, automated operation, and more consistent flow management. They are widely used in water treatment, power plants, oil &amp; gas, chemical processing, HVAC systems, and industrial automation projects. Suitable for on\/off or modulating flow control Available for ball, butterfly, gate, globe, and control valves Supports different voltage, signal, and actuator options Helps reduce manual operation and improve system efficiency Request a Quote Working Principle How Do Motor-Operated Valves Work? Motor-operated valves work by using an electric actuator to convert electrical energy into mechanical motion, allowing the valve to open, close, or regulate flow automatically. 01 Signal Input The control system sends an electrical signal to the actuator. Depending on the application, the signal can be simple open\/close control or a modulating signal such as 4\u201320mA or 0\u201310V. 02 Actuator Motor Starts After receiving the signal, the electric actuator motor begins to rotate. The motor drives a gear mechanism that increases torque and controls the movement speed of the valve stem or shaft. 03 Valve Stem or Shaft Moves The actuator transfers torque to the valve stem or shaft. For rotary valves such as ball valves and butterfly valves, the shaft turns 90 degrees. For linear valves such as gate or globe valves, the stem moves up and down. 04 Flow Is Controlled As the valve disc, ball, gate, or plug changes position, the flow path is opened, closed, or partially adjusted. This allows the system to control liquid, gas, or steam flow without manual operation. Electric Actuator The Role of the Electric Actuator The electric actuator is the key component of a motor-operated valve. It provides the torque required to move the valve and controls the valve position according to signals from the control system. On\/off actuator: fully opens or closes the valve for isolation control. Modulating actuator: adjusts the valve position for precise flow regulation. Limit switches: stop the motor when the valve reaches the open or closed position. Position feedback: sends valve position information back to the control system. Manual override: allows hand operation during power failure or maintenance. On\/Off Electric Actuator Modulating Electric Actuator Product Selection Motor-Operated Valve Types We Supply Our motor-operated valves are available in ball valve, butterfly valve, globe valve, gate valve, and knife gate valve designs. Each valve type is suitable for different flow control requirements, media conditions, and installation environments. Motor-Operated Ball Valves Motor-operated ball valves are ideal for fast on\/off control and reliable shutoff in water, gas, oil, and general industrial pipelines. Best for: quick isolation, tight sealing, compact pipeline systems. View Motor-Operated Ball Valves Motor-Operated Butterfly Valves Motor-operated butterfly valves are suitable for large-diameter pipelines, water treatment, HVAC, cooling water, and low to medium pressure systems.

View Motor-Operated Butterfly Valves Motor-Operated Globe Valves Motor-operated globe valves are designed for flow regulation, throttling service, steam systems, and process control applications. Best for: modulating control, precise adjustment, process flow regulation. View Motor-Operated Globe Valves Motor-Operated Gate Valves Motor-operated gate valves are used for full-open or full-close pipeline isolation where low pressure drop and straight-through flow are required. Best for: full-bore isolation, low flow resistance, main pipeline shutoff. View Motor-Operated Gate Valves Motor-Operated Knife Gate Valves Motor-operated knife gate valves are suitable for wastewater, slurry, pulp, mining, and media containing suspended solids. Best for: slurry handling, wastewater, pulp, mining, and solids-containing media. View Motor-Operated Knife Gate Valves Applications Applications of Motor-Operated Valves Motor-operated valves are widely used in automated flow control systems where remote operation, stable shutoff, and reliable process control are required. Different valve types can be selected according to the medium, pressure, temperature, and control requirements. Typical Industries Water Treatment Power Plants Oil &amp; Gas Chemical Processing HVAC Systems Mining &amp; Slurry Handling 01 Water Treatment In water treatment plants, motor-operated valves are used for automatic flow control in raw water intake, filtration systems, sedimentation tanks, pumping stations, backwash lines, and wastewater discharge systems.
