Rotary actuator AC/DC 24 V, 2 Nm
The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the
position defined by the control signal.
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°
Manual operation with lever possible (the gearing is disengaged for as long as the self-resetting
Manual override
lever is pressed).
The actuator is overload-proof and automatically stops when the end stop is reached.
The actuator switches off for seven seconds in the case of blocking, then attempts to restart. If
the blocked condition persists, the actuator attempts to restart once every two minutes a total of
15 times and subsequently once every two hours.
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.
