The Fisher CV500 has the same robustness as the Fisher CV500 eccentric cock control valve, but uses the segmented ball core as a control assembly rather than as a spool. The CV500 has a higher capacity than the V500 and has an equal percentage feature for better control performance. Both valves use spline spindles that do not idle when attached to the Fisher rotary actuator. Fisher CV500 eccentric cock control valve is a flanged or clipped eccentric valve with a reversible metal seat and spline shaft.
1.Excellent flow characteristics — precision profile machining of V-groove ball valves provides corrected equal percentage flow characteristics.
2.High flow capacity – the uncapped through-flow design provides higher flow capacity than many conventional ball valves and rotary eccentric valves
3.Long Seat Life – Patented V-Grooved Ball Valves roll in and out of the seat, * minimizing contact with the seat, thereby reducing wear and friction V-Grooved Ball Valves do not contact the seat during throttling operation.
4.Single piece body – the body is a single piece casting. Therefore, there will be no leakage of sealing gasket due to pipeline pressure.
5.Multi-function operation – self-centering seats and robust v-grooved ball valves allow for tight shutoff in any direction up, allowing forward or reverse flow
6.Easy to install – One-piece valve flanges can be matched with many different types of pipe flanges to meet various pipe requirements.Flanges minimizes exposed pipe flange connections, shortens alignment and installation time, facilitates installation of safety valves, and improves pipe tightness. Fisher CV500 eccentric cock control valve automatically centering when the pipeline is connected, easy to install.
7.Easy to assemble and maintain — no special positioning, precise clamping or repeated centering of V-shaped grooved ball core and valve seat is required when tightening the retainer, which facilitates accurate alignment and simplifies assembly
8.Acid resistance – trims and bolt materials are ideal for applications that handle acidic fluids and gases.Its structure meets the requirements of NACE MR0175-2002.
9.Rugged construction, sturdy seat and ball valve close tight.Large diameter shafts and strong spool components can withstand large pressure drops.
10.Reliable performance – patented seat with self-centering, self-lapping and dynamically aligned v-grooved ball core design for excellent cycle life with optional sealed metal shafts
