  • 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.

    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).
