Features
 

• Mode of operation  The actuator moves the ball valve to the operating position at the same time as tensioning the return spring. The ball valve is turned back to the safety position by spring force if the supply voltage is interrupted.


• Simple direct mounting Straightforward direct mounting on the ball valve with only one screw. The mounting position in relation to the ball valve can be selected in 90°<) steps.


• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.


• Flexible signalization Flexible signalization with adjustable auxiliary switch (0 ... 100%<) ).


• Combination valve/actuators Refer to the valve documentation for suitable valves, their permitted media temperatures and closing pressures.
