Datasheet

The Johnson Controls V-3000-6005 SPIDER FOR V-3000-1. Sold in package of 2. (74.95 ea.)

The V-3000 Series Pneumatic Valve Actuators are designed to accurately position steam or water valve modulating plugs in response to a pneumatic signal from a controller. Two models of the V-3000 are available; the exposed model is for installation in a protected location and the enclosed model is for installation in a location where the actuator would be subjected to tampering. A V-9502 Valve Positioner can be ordered separately for use on the exposed model only in applications where sequential operation is desired or additional positioning power is necessary; refer to the Specifications Table for ordering information.

Construction

Both models of the V-3000 have a molded synthetic rubber diaphragm design. This molded diaphragm provides a constant effective area throughout the valve stem stroke. All parts are protected by a sturdy die cast aluminum housing. The actuator assembly can be removed or repositioned by loosening a single set screw without disturbing the rest of the valve assembly.

Operation

With no control air pressure applied to the diaphragm, the valve is in the normal position. Spring and fluid forces in the valve combine to balance against the diaphragm pressure. Reducing the air pressure permits the valve spring to return the valve plug to its normal position.
