Page 2: Description
The Design CV500 Cam-Vee-Ball rotary control valve, valve are listed in table 1. has a Vee-BallR 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 Installation patented, self-centering seat, eccentrically rotating V-notch ball, and splined valve shaft. - Page 3 When ordered, the valve configuration and construction materials were 3. A Design CV500 valve is normally shipped as part selected to meet particular pressure, of a control valve assembly, with a power or manual pressure drop, temperature, and actuator mounted on the valve.
