Item # 10RVS9072, RVS Soft Seat Relief Valves

Series RVS relief valves utilize a soft seat design for reliable venting of gases at set pressuresfrom 1500 psi (103 bar) to 20000 psi (1378 bar). The operating temperature range is 32°F (0°C)to 400°F (204°C).

The soft seat design provides bubble tight sealing, repeatable pop-off, and reseat. Additionally,soft seat valves provide a higher cycle life than metal seat relief valves.

These precision valves are designed for pressure gas systems, where zero leakage is critical. Theyare not recommended for liquid nitrogen or liquid carbon dioxide, which produce gas at cryogenictemperatures upon relief.

Relief valves are designed to open proportionally to increasing pressure. Therefore, they are notrecommended for applications requiring immediate full valve flow at set pressure (such asdecompositions, polymerizations, etc.). Full flow of relief valve is defined at 10% overset pressure.

Options: Autoclave Engineers can supply variousinlet and outlet connections on special order.

1. AE relief valves are preset and factory sealed.Warranty is voided if seal is broken by customer.
2. Maximum system operating pressure should notexceed 90% of relief valve set pressure.Operating pressures in excess of this may causeweepage resulting in damage to the plugand seat.

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

For prompt service, Autoclave stocks select products.Consult factory.
All general terms and conditions of sale, including limitations of our liability, apply to all products and services sold
