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.
