Product features
Mode of operation
The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the
position dened by the control signal.
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.
Manual override
Manual operation with lever possible (the gearing is disengaged for as long as the self-resetting
lever is pressed).
High functional reliability
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.
Combination valve actuators
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.
