A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for use in high pressure applications.
When in neutral the HPD42-S52 blocks flow between all ports. On remote pilot signal at 1, the valve’s spool shifts to allow flow between ports 2, 3 and 4. 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. Pressure at port 5 will increase the required pilot pressure at a 1:1 ratio.
