  • Technical Feature

    OPERATION

    The valve is normally closed, pressure-limiting valves used to protect hydraulic
    components from pressure transients. When the pressure at the inlet (port
    ) reaches
    the valve setting, the valve starts to open to tank (port
    ), throttling flow to limit the
    pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant,
    immune to silting and are very fast.
