Features
- The seat ring design self-centers, self-laps, and dynamically aligns with V-notch ball, giving superior cycle life.
- No special orientation, precision clamping, or repetitive centering of V-notch ball and seat ring is required when tightening the retainer, promoting accurate alignment and easy assembly.
- Precise contouring of V-notch ball provides a modified equal percentage flow characteristic.
- Unrestricted, straight-through, flow design provides greater capacity than many conventional globe and rotary eccentric plug valves.
- Integral valve flanges mate with many different classes of pipeline flanges, satisfying a variety of piping requirements.
- The V-notch ball cams into and out of the seat minimizing contact with the seat ring for reduced wear and friction.
Erosive applications take a toll on process availability
Availability is one of the key concerns in plants today. Repairing or replacing your valves repeatedly results in downtime and reduced productivity.
Rotary severe service is defined as rotary control valve applications in which service or process conditions lead to constant wearing of the valve. These conditions are caused by dirty, erosive, coking, corrosive, viscous, and other hard-to-handle fluids.
They can cause lack of process control, frequent maintenance, unacceptable operating life, and poor shutoff.
A control valve solution for dirty and erosive fluids
With Fisher V500 and CV500 rotary globe valves and their ability to battle erosion and control hard-to-handle fluids, you can reduce maintenance costs and increase plant availability.
Fisher V500 and CV500 rotary eccentric plug valves are designed for erosive process applications, built tough for control, and intended for performancedemanding situations. They are known for their ability to fight off the effects of hard-to-handle fluids with rugged components and application versatility. The V500 valve has been proven in tough applications across multiple industries since being introduced in 1984.
Additional Benefits of V500 and CV500 Valves
• Extend Operating Life: Both sides of the seat ring have a shutoff surface, allowing it to be flipped over to extend operating life. The seat ring also self-centers, self-laps, and dynamically aligns with the plug to consistently achieve the ANSI Class IV leakage protection you need.
• Take Advantage of Reverse Flow: For erosive applications, the recommended flow direction for V500 and CV500 valves is with the shaft upstream, so that high-velocity flow is isolated in the port or outlet area. Erosion-resistant materials help protect the seat ring and retainer for easier maintanence.
• Achieve Higher Performance: When coupled with a Fisher pneumatic actuator and FIELDVUE™ DVC6200 digital valve controller, the V500 or CV500 valve assembly provides excellent installed performance. It helps control closer to setpoint, extends operating life, and battles erosion effectively in your most critical processes.
