Johnson Controls VA-3100-HGC Electric Valve Actuator W/Auxiliary Switches-2 NSR 24V 0-10 VDC

The Johnson Controls VA-3100-HGC Electric Valve Actuator is quite standard and performing to offer control valves in intricate HVAC systems. It operates on a typical 24V AC supply voltage and accepts a 0-10 VDC proportional control voltage for fine tuning. When a voltage is supplied, which opens a linked valve through an accurate ½" travel. This proportional control provides a precise control of either water or air throughout the heating and air conditioning system. The design of NSR is also advantageous in that valve remains in the last position whenever there is power failure.
