DIRECTIONAL VALVES
PD42-S60N Piloted, 2-Position, 4-Way Spool
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, 2-position, 4-way, spool-type, hydraulic
directional valve.
OPERATION
In the neutral position, the PD42-S60N allows flow between ports 2 and 3 and from 4
to 5. On remote pilot signal at 1, the valve shifts to allow flow between ports 3 and 4,
and from 2 to 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 2, 3, and 4 without affecting required
pilot pressure. Pressure at 6 will affect required pilot pressure.
FEATURES
• Hardened spool and cage for long life.
