Johnson Controls V-3801-8001 4-13/32″ Dia. Pneumatic Valve Actuator

Johnson Controls V-3801-8001 Pneumatic Valve Actuator.
Applications The V-3801-8001 Valve Actuator is used on 1/2 and 3/4 in. VG7000 Series Valves.
The V-3801-8001 is not recommended for sequencing because its relatively small size and small output force may result in unacceptable spring shift.
The V-3801-8001 Pneumatic Valve Actuator is designed to accurately position steam or water valve modulating plugs in response to a
pneumatic signal from a controller. The small oval top makes the V-3801-8001 ideally suited for 1/2 and 3/4 in. VG7000 Series valve
applications with restricted mounting space. This actuator has a molded synthetic rubber diaphragm design. The molded diaphragm
provides a constant effective area throughout the actuator stroke. All parts are protected by a sturdy die-case aluminum housing.
