The HPE42-S67D is a high pressure, screw-in, cartridge-style, proportional, spring-centered spool, pilot-operated, hydraulic directional valve.
In neutral position inlet port 3 is blocked and ports 2, 4 and 5 are connected to each other. On remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to allow flow from port 3 to 4, thru a load such as a hydraulic cylinder or motor, and from port 2 to 5 and to tankt. Port 5 is to be used as tank port only with maximum pressure of 69 bar (1000 psi). On remote pilot signal at port 6 the spool shifts proportionally to the applied force in the opposite direction, thus reversing the flow direction. The spool is symmetrical and provides meter-in and meter-out control.
