SP4P1-B4 Proportional, Pilot-Operated Reducing / Relieving Valve

for proportional control of hydraulic clutches

The pilot-operated reducing valve SP4P1-B4 is a screw-in, cartridge-style, spool-type hydraulic pressure reducing / relieving valve which allows to adjust the reduced pressure in a defined range. Pressure level is proportional to DC current excitation.
