A cartridge-style direct-acting spool-type pressure reducing/relieving valve

Technical Feature

OPERATION:
In its steady state, the valve allows flow to pass bi-directionally from ② to ①， with the spring chamber constantly drained at ③． On attainment of a pre-determined pressure at ① , the cartridge shifts to restrict input flow at ② , thereby regulating pressure at ① . In this mode, the valve will also relieve ① to ③ at approximately 10 bar over the reducing setting.
