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.
