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 .Dead band (from reducing to relieving) pressure rise over reduced pressure setting:
Non-flow condition: approximately 0.55 bar (8 psi); with flow: approximately 2.1 bar(30
psi). -
