The V-3000-8012 and V-3000-8003 Pneumatic Valve Actuators are designed to accurately position steam or water valve modulating plugs in response to a
pneumatic signal from a controller. A V-9502 Valve Positioner can be ordered separately for use with the V-3000-8012 only, in applications where sequential
operation is desired or additional positioning power is necessary. The actuators have a molded synthetic rubber diaphragm design. This molded diaphragm
provides a constant effective area throughout the actuator stroke. All parts are protected by a sturdy die-cast aluminum housing. Two models are available. The exposed model (V-3000-8012) is designed for installations in a protected location, and the enclosed model (V-3000-8003) is designed for installation in a location
where the actuator could be subjected to tampering.
