Реферат: ABSTRACT A high temperature safety relief system for a pressure vessel including a pilot controlled main relief valve and an associated non-flowing pilot valve with high temperature metal or metal like seals for temperatures as high as around 1,000°F provided for both the main relief valve and pilot valve. The main valve body has a main body chamber in fluid communication with the inlet flow passage when the reciprocal piston valve member is in seated closed position. The movement of the piston valve member is cushioned during movement to open position and during movement to closed position. The non-flowing pilot valve has an elongate internal housing receiving the inlet line along its longitudinal axis and the housing is mounted for external rotational adjustment to control the blowdown pressure.
