Parker Autoclave's RVP Series relief valves are designed with a metal seat design for reliable venting of gases at set pressures from 3,000 psi (206 bar) to 75,000 psi (5171 bar). The operating temperature range is -423°F (-252°C) to 400°F (204°C).These precision relief valves are designed 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 in the catalog

Parker Autoclave 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.

• Research

Features/Benefits:
• Standard models of Relief Valves are constructed of 316 stainless steel with selected components made of anti-galling stainless steel material for optimum economy and ruggedness.
• Designed with 3/8” and 5/16” Parker Autoclave high pressure inlet connections. The outlet connection on all models is a female 3/4” NPT. While adapters to other sizes and connection types are available, they must be sized for specific flow requirements.
• Orifice diameters range from .062 (1.57mm) to .312” (7.92mm).
• Designed to open as a function of increasing system pressure. Proper spring selection assures repeatability of opening, full lift and flow, and reseat pressures.
• 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.
• Unique seat construction plus over-the-nozzle guiding and proper selection of materials permits standard set pressures to 75,000 psi. (5171 bar)
• Designed to provide bubble tight shut off of gases.
• Engineered to perform with fewer basic components, RVS valves facilitate minimum stocking of spare parts and ease of maintenance
• Available with CE Mark. SOG option available upon request.
