Description:
A cartridge-style direct-acting spool-type pressure reducing/ relieving valve.
Operation:
In its steady state, the valve allows flow to pass bi-directional 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.
