A Motorized Gate Valve is a standard gate valve integrated with an electric actuator (motor). This automation replaces manual handwheels, gears, or hydraulic/pneumatic operators, enabling remote or programmed control of the valve's opening and closing.
Remote Operation: Control valves from control rooms or remotely, improving safety (hazardous locations) and convenience (hard-to-reach valves).
Automation: Easily integrated into automated processes and control systems (SCADA, BMS, PLC).
Speed & Labor Saving: Faster operation than large manual valves; eliminates manual labor.
Programmable Control: Timed operation, sequencing, and integration with process logic.
Position Feedback: Provides crucial status information to operators and control systems.
Fail-Safe Capability: Enhances process safety and environmental protection.
Suitable for Large Sizes: Electric actuators effectively handle the high torque required for large diameter gate valves (e.g., DN40 and above).
