A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve.
When in neutral the PD16-S50 allows flow between ports 3 and 2 while blocking at 4. On remote pilot signal at 1, the valve’s spool shifts to allow flow between 3 and 4, while blocking at 5. 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 affect required pilot pressure.
• Hardened spool and cage for long life.
• 50, 70, 100 and 150 psi bias springs available.
