Features
 

Mode of operation At the same time as tensioning the return spring, the actuator pushes the ball valve to the operating position. If the supply voltage is disconnected, the ball valve is returned to the safety position by spring force.

Simple direct mounting Only one screw is required for direct attachment on the ball valve. In 90°) steps, the mounting position in relation to the ball valve can be selected.

High functional reliability The actuator is overload-proof, does not require limit switches, and stops when the end stop is reached automatically.

Combination valve/actuators For information on acceptable valves, their permissible media temperatures, and closing pressures, consult the valve documentation.
