  • 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.
