Mode of operation
The actuator moves the valve to the operating position at the same time as tensioning the return spring. The valve is turned back to the fail-safe position by spring force when the supply voltage is interrupted.

Simple direct mounting

Simple direct mounting on the ball valve with only one screw. The mounting orientation in relation to the ball valve can be selected in 90° steps.

High functional reliability

The actuator is overload protected, requires no limit switches and automatically stops when the
end stop is reached.

Flexible signalling

With adjustable auxiliary switch (0...100%)
