(3) Series RVS relief valves utilize a soft seat design for reliable venting of gases at set pressures from 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. They are not recommended for liquid nitrogen or liquid carbon dioxide, which produce gas at cryogenic temperatures upon relief.
Relief valves are designed to open proportionally to increasing pressure. Therefore, ...
