Autoclave 5RVP9072-CE Relief Valve

Autoclave 5RVP9072-CE Relief Valve

Medium Pressure, High Pressure and NPT Inlet Options to 75,000 psig

Principle of Operation:

Parker Autoclave Engineers relief valves open proportionally to increasing pressure. Therefore, 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:

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 however, not recommended for steam boiler applications nor are they ASME code stampable (K-Factors are not available).

Features and Benefits:

• Material: standard models are constructed of UNS S31600, 316 cold worked stainless steel with selected components made of anti-galling stainless steel material for optimum economy and ruggedness.
• 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%.
• Re-Seat Pressure: 85% of set pressure
• Dependable Shut-Off: series RVP relief valves provide shut-off of liquids and gases under pressure to commercial tightness standards.
• Fewer Parts, Ease of Maintenance: engineered to perform with fewer basic components, RVP valves facilitate minimum stocking of spare parts and ease of maintenance. The combined angle seat in the RVP series eliminates the need for lapping in rework.

All models are designed primarily for thermal expansion or low volume relief applications at high pressures where flow is not critical.
Note: these flow curves are based on capacities of valves only and do not take tubing into account.

Relief Valve Options (add the following suffixes to the valve part number):

• “HT“: High Temperature Spring to 750°F (RVP or PRVP series only)
• “K“: Anti-vibration collet/gland assembly (cone & thread connections only)
• “HYG“: Modified for use with Hydrogen / Helium (seat surface and Helium seat tested; no material changes)

Notes:

• Parker Autoclave Engineers relief valves are complemented by a complete line of high pressure fittings and tubing.
• Traceability is ensured by use of heat and purchase order codes etched on relief valve body that also include model number, MAWP rating, and material type references.
• All relief valves include connection collar and gland nut unless requested otherwise.
• Maximum pressure rating based on the lowest rating of any component. Actual working pressure may be determined by tubing pressure rating, if lower.

Caution:

1. Parker Autoclave relief valves are preset and factory sealed. Warranty is voided if seal is broken by customer.
2. Maximum system operating pressure should not exceed 90% of relief valve set pressure. Operating pressures in excess may cause weepage resulting in damage to the plug and seat.
3. Relief Valves are not to be used as pressure regulators, RVP has limited actuation life dependent on pressure.
