HPD16-S50 HyPerformance (HPD16-S50)
A high pressure, screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve.
Product Operation
When in neutral, the HPD16-S50 allows flow between ports 3 and 2 bidirectionally while port 4 is blocked. On remote pilot signal at 1, the valve’s spool shifts to block port 2 while opening flow between ports 3 and 4 bidirectionally. The spring chamber is vented to the tank through port 5. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, and 4 without affecting required pilot pressure at port 5. Pressure at port 5 will increase the required pilot pressure at a 1:1 ratio.
