Parker / Autoclave Engineers FCD - RVP Metal Seat Relief Valves

Series RVP relief valves provide reliable venting of gases or liquids for set pressures from 3000 psi (206 bar) minimum to 75000 psi (5171 bar). The standard temperature range for all models is -423° to 400° (-252° to 204°C). A high temperature option to 750°F (399°C) 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.

All RVP models are designed primarily for thermal expansion or low volume relief applications at high pressures where flow is not critical. Thus, liquid curves for these models are not shown.

Options: Autoclave Engineers can supply various inlet and outlet connections on special order. A high temperature option is also available for temperatures to 750°F (399°C) for RVP models.
To specify high temperature option: Add suffix “HT” for 750°F (399°C) high temperature option.

Caution:
1. AE 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 of this may cause weepage resulting in damage to the plug and seat.

Ordering Instructions: To permit prompt and correct responses to your order, we will require the following information: quantity, valve catalog number, service requirements (liquid, gas & vapor), set pressure (PSIG - bar), and service temperature range.

Caution should be exercised in proper selection of medium pressure tubing based on actual operating conditions. Two series available: 15000 (1034 bar) and 20000 (1380 bar).

AE Relief Valves Features	N/A AE Relief Valves Features Materials: Standard models of Relief Valves are constructed of 316 stainless steel with selected componentsmade of anti-galling stainless steel material for optimum economy and ruggedness. Connections: All models except 30, 60, & 75 RVP series are designed with 9/16” Autoclave Medium Pressureinlet connections. The 30 & 60 RVP have 3/8” high pressure connection, while the 75 RVP has a5/16” high pressure connections. The outlet connection on all models is a female 3/4” NPT. While adaptersto other sizes and connection types are available, they must be sized for specific flow requirements. SeeAdapter section. Orifice Sizes: Orifice diameters range from .062 (1.57mm) to .312” (7.92mm). Full Lift for Full Flow: These relief valves are designed to open as a function of increasing systempressure. 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 combineto assure the highest quality, reliability and service life. Each valve is preset and factory sealed to ensureproper valve operation. High Set Pressure Capability: Unique seat construction plus over-the-nozzle guiding and proper selection ofmaterials permits standard set pressures to 75,000 psi. (5171 bar) Dependable Shut-off: Series RVP relief valves are designed to provide shut-off of liquids and gases underpressure to commercial tightness standards. Fewer Parts, Ease of Maintenance: Engineered to perform with fewer basic components, both RVP andRVS valves facilitate minimum stocking of spare parts and ease of maintenance. The combined angle seat inthe RVP series eliminates the need for lapping in rework. Special Requirements: Most models available with CE Mark. SOG option available upon request.
