Product features
Simple direct mounting Straightforward direct mounting on the ball valve with only one screw. The mounting position in
relation to the mixing valve can be selected in 90° steps.
Manual operation Manual operation possible by lever (temporary disengagement of the gearing latch by pressing,
permanent disengagement by means of the rotary knob on the housing).
Functional reliability The actuator switches off automatically when the end stops are reached.
Combination valve actuators Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.
Note
Connect via safety isolation transformer.

Adjusting auxiliary switch
1. Remove the cover of the housing.
2. Press down the manual disengagement A on the actuator and turn the actuator into the
required switching position of the auxiliary switch by means of the lever.
3. Insert the cam ring B as shown in Fig. 1, so that the switching point C just about operates the
switch. Connection S1–S2 is switched (the arrow D is now at the top).
4. Assemble the cover of the housing.
