Seat Tightness of Pressure Relief Valves - API
ballots.api.orgThis standard describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs. The maximum acceptable leakage rates are defined for pressure relief valves with set pressures from (103 kPa gauge) 15 psig to 41,379 kPa gauge (6,000 psig).
