A screw-in cartridge, direct acting, spool type, pressure reducing/relieving valve, intended for use as a pressure control device, which can proportionally control the reduced pressure across the specified range using variable electrical input signal. Reduced pressure output is proportional to DC current input. This valve maintains a constant reduced pressure regardless of pressure variations in the primary system. In addition to the reducing function, this valve also provides a relief function from the reduced pressure port to the tank port if pressure in the secondary circuit exceeds the set pressure.
