A high pressure, proportional, pilot-operated, screw-in, cartridge-style, spool-type, hydraulic directional valve.
In the neutral position, the HPE42-S62 allows flow between ports 2 and 3 and between ports 4 and 5 bidirectionally. When the remote pilot signal at 1 exceeds the force of the bias spring, the spool shifts proportionally to the applied pilot pressure to gradually close flow paths until the spool is fully shifted, blocking all ports.
The spring chamber is vented through port 6. Pressure at port 6 will directly (1:1)
affect the pilot pressure required and must be added to bias spring value.
