    OPERATION

    Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at the
    inlet (port
    ) to a constant reduced pressure at port , with a full-flow relief function from
    port
    to tank (port ).Pressure at port is directly additive to the valve setting at a 1:1
    ratio and should not exceed 350 bar.


    Recommended maximum inlet pressure is determined by the adjustment range.
    Ranges D, E, N, and Q are tested with a 2000 psi (140 bar) maximum differential between
    inlet and reduced pressure.
    Ranges A, B, and H are tested with a 3000 psi (210 bar) maximum differential between inlet
    and reduced pressure.
    Ranges C, and W are tested with a 5000 psi (350 bar) of inlet pressure.
