3-Piece Motorized Ball Valve
The FLE-Q-3PS 3-piece motorized ball valve combines a serviceable stainless-steel three-piece body with electric quarter-turn actuation for automated shutoff and process isolation. Its center body can be accessed more easily for seat, seal and internal maintenance, making it especially suitable for equipment, utility and process lines where long-term serviceability matters.

Designed for systems where maintenance access matters
The defining advantage of a 3-piece electric ball valve is not simply the number of body sections—it is the ability to separate the center valve body from the end connections for easier internal service.
Compared with a compact one-piece or conventional two-piece valve, the FLE-Q-3PS gives maintenance teams better access to seats, seals, ball and stem components. This is valuable on packaged skids, utility lines and process equipment where valve replacement would otherwise create more piping work and downtime.
- 01Center-body access simplifies inspection, cleaning and seal replacement.
- 02Stainless-steel construction supports water, oil, air, gas and compatible process media.
- 03Full-port style flow paths can minimize pressure loss in open position.
- 04Electric automation reduces manual operation and supports remote equipment control.

Service the valve body without treating the assembly as disposable
For OEM equipment and industrial plants, the real value of a three-piece ball valve appears after installation: easier access to wear components can reduce replacement work and simplify planned maintenance.
3-piece vs 2-piece electric ball valve
Both can automate shutoff. The main difference is serviceability: the 3-piece structure is selected when internal maintenance access is an important part of the project lifecycle.
Remote isolation with control options matched to the equipment
Actuator selection should follow the valve torque, operating frequency, power supply, control signal and site environment—not voltage alone.
Where 3-piece motorized ball valves add value
The strongest applications are compact process and equipment lines that need reliable automatic shutoff today and practical maintenance access later.

Automatic isolation around filters, pumps, dosing units and packaged treatment equipment.

Serviceable electric shutoff for compact skids, machinery modules and process packages.

Stainless-steel automated isolation where material compatibility and maintainability are both important.

Remote shutoff for auxiliary air, gas and utility lines in industrial equipment and plants.
Select the valve around serviceability and process duty
A 3-piece body is valuable only when the material, seat, thread, actuator torque and control architecture are also correct for the real operating conditions.
Define the medium
Identify water, oil, gas, steam or chemical composition and check stainless-steel and seat compatibility.
Confirm pressure & temperature
Use actual operating and design values so seat material and actuator torque are not selected from nominal size alone.
Select seat material
Choose PTFE, Nylon or PPL according to temperature, sealing duty and process compatibility.
Match thread standard
Confirm GB, ANSI, JIS or DIN thread requirements before ordering the valve body.
Define maintenance access
Allow enough space for safe depressurization, body-bolt removal and future seat or seal replacement.
Specify actuator control
Select on/off, regulating, intelligent or selected hazardous-area actuation together with voltage and feedback needs.
Built for repeatable industrial automation
The valve package combines stainless-steel ball-valve construction with electric actuator options for remote operation, status feedback and industrial automation.
