Mounting on the valve
Before mounting the actuator, position the rotary valve
according to its installation instruction.
Operation
The actuator is powered by a synchronous motor. The
spindle of the actuator rotates 90°. In the end positions the
motor is switched off by endswitches.
Manual operation declutches the gear from the valve. As
soon the actuator is powered, the valve is driven by the
actuator again.
There is no adjustment necessary.
