PD16-S61N Valve

SYMBOL:
PD16-S61N Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic directional valve.

OPERATION
In neutral position, the PD16-S61N allows flow between ports 2 and 3 and between ports
4 and 5. On remote pilot signal at 1, the valve shifts to allow flow between ports 3 and 4,
while blocking ports 2 and 5. The spring chamber is vented to the tank through port 6. The
vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, 4 and 5
without affecting required pilot pressure. Pressure at 6 will affect required pilot pressure.

FEATURES
• Hardened spool and cage for long life.
• 60, 110 and 170 psi bias springs available.
