HPD42-S61 HyPerformance™ Piloted 4-Way Spool (HPD42-S61)
A high pressure, spool-type, screw-in, cartridge-style, pilot-operated, hydraulic directional valve.
Product Operation
When in neutral the HPD42-S61 allows flow between ports 2 and 3, and between ports 4 and 5. On remote pilot signal at 1, the valve’s spool shifts to allow flow between 3 and 4 while blocking 2 and 5. The spring chamber is vented to the tank through port 6. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, 4 and 5 without affecting required pilot pressure. Pressure at port 6 will increase the required pilot pressure at a 1:1 ratio.
