PD10-51 Valve

SYMBOL:
PD10-51 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve.

OPERATION
In neutral (unpiloted), the PD10-51 allows flow between ports 2, 3 and 4. On remote
pilot signal at 1, the valve shifts to block all ports. 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 5 will affect
required pilot pressure.

FEATURES
• Hardened spool and cage for long life.
• 150 and 250 psi bias springs available.
