Autoclave R20RVS Repair Kit
Principle of Operation:
Parker Autoclave Engineers relief valves open proportionally to increasing pressure. They are not recommended for applications requiring immediate full valve flow at set pressure and should not be considered a “Safety Valve”. Full flow of relief valve is defined as 110% of set pressure.
RVP Metal Seat Relief Valve Features:
Series RVP relief valves provide reliable venting of gases or liquids for set pressures from 3,000 psi minimum to 75,000 psi. The standard temperature range for all models is -423° to 400°F. A high temperature option to 750°F is also available.
These precision valves are designed for pressure gas systems, cryogenic systems, petrochemical applications and other special systems. Capable of handling air, gases, steam, vapor and liquids, they are not recommended for steam boiler applications nor are they ASME code stampable (K-Factors are not available).
RVS Metal Seat Relief Valve Features:
Series RVS relief valves utilize a PEEK soft seat design for reliable venting of gases at set pressures from 1,500 psi to 20,000 psi. The operating temperature range is -50° to 400°F.
The soft seat design provides bubble tight sealing, repeatable pop-off, and reseat. Additionally, soft seat valves provide a higher cycle life than metal seat relief valves.
These precision valves are designed for gases and liquid systems where zero leakage is critical. They are not recommended for liquefied gases which produce gas at cryogenic temperatures below -50°F upon relief.
Features and Benefits:
- Material: Standard models constructed in UNS S31600, 316 cold worked stainless steel with selected components made of anti-galling stainless steel material for optimum economy and ruggedness.
- Orifice Sizes: Orifice diameters range from .062″ to .312″.
- Full Lift for Full Flow: These relief valves open as a function of increasing system pressure. Proper spring selection assures repeatability of opening, full lift and flow, and reseat pressures.
- Reliability and Long Service Life: Materials engineering and stringent quality control procedures combine to assure the highest quality, reliability and service life. Each valve is preset and factory sealed to ensure proper valve operation. Note: mount as far from pump outlet as possible to avoid premature relief and extend valve life.
- Setpoint Accuracy: setpoint accuracy is ±3% and re-seat pressure is 85% of set pressure.
- High Set Pressure Capability: Unique seat construction plus over-the-nozzle guiding and proper selection of materials permits standard set pressures to 75,000 psi.
- Dependable Shut-Off: Series RVP/PRVP relief valves provide shut-off of liquids and gases under pressure to commercial tightness standards. Series RVS/PRVS relief valves provide bubble tight shut off of gases and liquids.
- Fewer Parts, Ease of Maintenance: Engineered to perform with fewer basic components, both RVP/PRVP and RVS/PRVS valves facilitate minimum stocking of spare parts and ease of maintenance. The combined angle seat in the RVP/PRVP series eliminates the need for lapping in rework.
