Pilot-operated safety relief valves: A simple, effective ...
www-eng.lbl.govWith a POSRV, as system pressure increases, seat tightness also increases. By contrast, the seating forces of a direct spring-operated valve are essentially a simple force to close (spring) against a force to open (system pressure). This difference means that the pilot valve has greater seat tightness at higher system operating pressures.
