Our electric actuator is specially desinged for quarter turn operating. 

Our electric actuator can be applicable to a butterfly valve, ball valve, anything required to turn a quarter. Our quarter-turn electric actuators are designed to provide torque ranges from  15 N.m to  3000 N‧m. 

* Indicator : Continuous mechanical indicator with arrow 

* Manual override : Declutching mechanism 

* Self locking : Provided by double worm gearing 

* Mechanical stopper : 2 each external adjustable screws 

* Space heater : 10W(110/220V AC) anti-condensation 

* Material : Aluminum alloy, steel, Al bronze, polycarbonate 

Our quarter turn electric actuator is utilized with self-locking to prevent valves from being back driven and provide actuators with stable and reliable operation.

ISO 5211 Flange connection is used for mounting actuators to valves and a raised mechanical position indicator is used to enable the operators to identify the valve position. The clutch-less design enables the actuators to be changed from electrical control to manual operation without clutch or brake to achieve easier operation thus increases mechanical reliability and decrease the failure rate.
