Technical Feature
OPERATION
Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at
the inlet (port ② ) to a constant reduced pressure at port ① , with a full-flow relief
function from port ① to tank (port ③ ). Pressure at port ③ is directly additive to the
valve setting at a 1:1 ratio and should not exceed 210 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 5000 psi (350 bar) of inlet pressure.
