How do pressure safety valves work
WebPilot operated safety valves are controlled by the process medium in which they operate. To achieve this, system pressure is fed to the pilot valve (= control component for the main valve) via the pressure tapping line which uses the space in the dome above the main valve piston to open and close the main valve. WebMay 21, 2024 · When the system pressure (P1) is between 7% and 15% below the set pressure (for Nacional Valves) the valve is able to close and the seal against the valve nozzle/seat is restored.
