Electric Actuated Valve

Electric Actuated Valve Supplier in Dubai, UAE Valves delivers motorized valve packages that ensure reliable isolation and precise control in process networks where plant air is limited or unavailable. An electric actuator applies controlled torque and speed to the valve stem, enabling repeatable on/off duty, quiet operation, and smooth integration into plant automation. We supply complete electric actuated ball, butterfly, gate, globe, knife gate, and plug valves for new projects and upgrades across the Middle East.

How Electric Actuated Valves Work

A compact motor drives a gear train to rotate or lift the valve stem. Limit switches define open and closed positions, while torque switches prevent overload. For control duty, an electronic module interprets a 4–20 mA or 0–10 V signal and positions the valve with feedback to the DCS or PLC. Local selectors allow open, stop, and close from the field. Fail last, fail in place, or battery backed fail open or fail close options provide a defined safe state. Enclosures are sealed against dust and water, with ATEX or IECEx certification available for hazardous areas.

Benefits of Electric Actuated Valves

• Accurate positioning and steady control without plant air
• Simple integration with DCS or PLC using analog or digital signals
• Non intrusive setup and local controls for quick commissioning
• Lower maintenance than pneumatic systems in many services
• Quiet operation with power used only during movement
• Reduced lifecycle costs with fewer auxiliary systems
