through 8 Fisher V500 eccentric plug rotary control valves. Refer to separate manuals for information concerning the
actuator and accessories.
Do not install, operate, or maintain a V500 valve without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to
carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

Description

The V500 rotary control valve is a flanged (figure 1) or flangeless valve with a self-centering seat, eccentrically rotating
plug, and splined valve shaft. Suitable for forward or reverse flow use, this valve mates with a variety of actuators to
provide throttling or on-off service. Both flanged and flangeless valves mate with CL150, 300, or 600 raised face
pipeline flanges or DIN PN10 through PN100 flanges.

    If the valve has ENVIRO‐SEALt live‐loaded packing installed readjustment will probably not be required. See the Emerson Automation Solutions instruction manual entitled ENVIRO‐SEAL Packing System for Rotary Valves (D101643X012) for packing instructions. If you wish to convert your present packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the Parts Kit section later in this manual.
