DIRECTIONAL VALVES
PD16-S60N Piloted 4-Way Spool
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve.
OPERATION
In the neutral position, the PD16-S60N allows fl ow between ports ➁ and ➂, and
from
➃ to ➄. On remote pilot signal at ➀, the valve shifts to allow fl ow between ➂ and
➃ and from ➁ to ➄. The spring chamber is vented to the tank through port ➅. The
vented spring chamber allows the valve to be fully pressurized at ports
➀, ➁, ➂ and
➃ without affecting required pilot pressure. Pressure at port ➅ will affect required
pilot pressure.
FEATURES
• Hardened spool and cage for long life.
• 60, 80, 110 and 170 psi bias springs available.
