AC230V Electric Actuator Features

Simple direct mounting Simple direct mounting on the globe valve by means of form-fit hollow clamping jaws. The actuator can be rotated by 360° on the valve neck.
Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).
The stroke can be adjusted by using a hexagon socket screw key (4 mm), which is inserted into the top of the actuator. The stroke shaft extends when the key is rotated clockwise.
High functional reliability The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.
Combination valve/actuator Refer to the valve documentation for suitable valves, their permitted fluid temperatures and closing pressures.
Position indication The stroke is indicated mechanically on the bracket with tabs. The stroke range adjusts itself automatically during operation.
Home position Factory setting: Actuator spindle is retracted.
When valve-actuator combinations are shipped, the direction of motion is set in accordance with the closing point of the valve.
Setting direction of stroke When actuated, the stroke direction switch changes the running direction in normal operation.
