NV24-3 US

 

Application
For on/off, floating point control of globe valves. Actuator will mate to an integrated adaptor bracket.

 

Functional safety
The actuator is secured against short circuiting and incorrect polarity. The stroke is adapted automatically and is overloadprotected.

 

Manual operation
When a 3/16 or 5 mm hex is inserted and turned clockwise, the actuator plunger pushes out. The actuator plunger retains the position until the nominal voltage is applied.
