Fisher CV500 Valve is a flanged or flangeless eccentric plug valve with reversible metal seat ring and splined shaft. The CV500 combines the rangeability of the cammed-segmented V-notched ball, with the inherent ruggedness found in the V500 heavy duty bearings, seals and body making it suitable for the pressure control for gas and liquids.
The flanged CV500 valve features streamlined flow passages, rugged metal trim components, and a self-centering seat ring.
The Fisher CV500 valve dependably controls fluids in many process industries as the flow design provides high capacity for gas, steam, liquids, or fibrous slurries.
1. The reversible seat is not available in every trim material. 2. The pressure or temperature limits in the referenced tables or figures, and in any applicable code limitation, should not be exceeded. 3. Ratio of maximum flow coefficient to minimum usable flow coefficient. May also be called rangeability
See how Fisher Control Valves provide safe, efficient and intuitive flow control.
Fisher CV500 eccentric plug valves may be installed in any position. However, for best shutoff performance, a position with the shaft horizontal is recommended.

| Valve Body Sizes | NPS 3, 4, 6, 8, 10, and 12. DN 80, 100, 150, 200, 250 and 300 are also available. End |
| End Connection Style | Raised-face flanges or ring-type joint flanges (ASME B16.5). Valve bodies with EN PN10 through PN100 flanges also available. |
| Maximum Inlet Pressure(2) | Consistent with applicable ASME or EN flange ratings |
| 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 | Modified equal percentage |
| Flow Direction | Forward (normal) flow is into the convex side of the V-notch ball Bidirectional flow is into either side of the V-notch ball |
| Flow Coefficient Ratio(3) | 200 to 1 |
| Actuator Mounting | Right-hand or left-hand as viewed from the upstream side of the valve. Mounting position depends on the desired open valve position and flow direction required by operating conditions. For more information, see the Installation section. |
| Valve V-Notch Ball Rotation | Counterclockwise to close (when viewed from the actuator side of the valve body) through 90 degrees of V-notch 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 push-down-to-open (extending actuator rod opens valve body) |
