ratings
Maximum Pressure Drops
(1)
Shutoff Classification
Class IV per ANSI/FCI 70-2 and IEC 60534-4,
(0.01% of valve capacity at full travel), for either
flow direction
Flow Characteristic
Approximately equal percentage
Flow Direction
J
Forward (normal) flow is into the convex side of
the V-notch ball
J
Bidirectional flow is into either side of the
V-notch ball
Actuator Mounting
J
Right-hand or
J
left-hand as viewed from the

actuator side of valve body) through 90 degrees
of ball rotation
Valve Body/Actuator Action
With diaphragm or piston rotary actuator,
field-reversible between

push-down-to-close
(extending actuator rod closes valve body) and
J
push-down-to-open (extending actuator rod
opens valve body)

and Approximate Weights
1. The pressure/temperature limits in this manual and any applicable standard limitations should not be exceeded.
2. Shaft diameter and spline end must match available shaft diameter of actuator.
Description
The Design CV500 Cam-Vee-Ball rotary control
valve, has a Vee-Ball
r
style segmented ball in a
valve body similar to the Design V500 valve. The
Design CV500 is a flanged (figure 1) or wafer (figure
2) valve with a self-centering seat, eccentrically
rotating V-notch ball, 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 wafer valves
mate with ASME flanges or DN flanges.
No person may install, operate, or maintain a Design
CV500 valve without first
D
being fully trained and
qualified in valve, actuator, and accessory
installation, operation, and maintenance, and
D
carefully reading and understanding the contents of
this manual. If you have any questions concerning
these instructions, contact your Emerson Process
Management sales office before proceeding.
Specifications
Specifications for the Design CV500 rotary control
valve are listed in table 1 and 51.3:CV500.
