A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for use in high
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 ther required
pilot pressure at a 1:1 ratio.
