The actuator moves the buttery valve to the operating position at the same time as tensioning
the return spring. The buttery valve is turned back to the safety position by spring force if the
supply voltage is interrupted.
Straightforward direct mounting on the buttery valve with only one screw. The mounting position
in relation to the buttery valve can be selected in 90° steps.
Manual operation of the valve with the hand crank, locking in any position with the interlocking
switch. Unlocking is manual or automatic by applying the operating voltage.
Adjustable angle of rotation with mechanical end stop.
The actuator is overload-proof, requires no limit switches and automatically stops when the end
stop is reached.
The actuator has one auxiliary switch with a xed setting and one adjustable auxiliary switch.
They permit a 10% or 11 ... 100% angle of rotation to be signalled.
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.
