  • Technical Feature

    OPERATION:

    The valves are normally closed, pressure-limiting valves used to protect hydraulics
    components from pressure transients. Fast opening and closing is gained at the
    expense of smoothness. W hen the pressure at the inlet (port
    ①) reaches the valve
    setting
    , the valve starts to open to tank (port ② ), throttling flow to limit the pressure
    rise. These valves have low pressure rise vs. flow and are very fast.
    Back pressure on the tank port
    ② is directly additive to the valve setting at a 1:1ratio.
