More Information


Principle of operation:
The actuator is connected with a standard modulating signal of DC 0 ... 10V and 
travels to the position defined by the positioning signal. The measuring voltage U 
serves for the electrical display of the actuator position 0 ... 100% and as slave control 
signal for other actuators.
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 - temporary, permanently. The gear is 
disengaged and the actuator decoupled for as long as the button is pressed / latched. 
The stroke can be adjusted by using a hexagon socket screw key (5 mm), which 
is inserted into the top of the actuator. The stroke spindle 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 medium 
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
Setting ex-works: 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.
Direction of stroke switch
When actuated, the direction of stroke switch changes the running direction in normal 
Adaption of stroke range
The first time the supply voltage is switched on, i.e. at the time of commissioning, the 
actuator carries out a stroke adaption, which is when the operating range and position 
feedback adjust themselves to the mechanical stroke.
Manual triggering of the adaption can be carried out by pressing the "Adaption" button.
The actuator then moves into the position defined by the positioning signal.
