DIRECTIONAL VALVES
PD42-S67B Piloted, 4-Way Spool-Type Valve
DESCRIPTION
A screw-in, cartridge-style, pilot-operated spool-type hydraulic directional valve.
OPERATION
When the PD42-S67B is in neutral position, fl ow is allowed between ports ➁, ➂ and
➄. When the remote pilot signal at ➀ exceeds the force of the bias spring, the spool
shifts to allow fl ow between
➂ and ➃, and between ➁ and ➄. On remote pilot signal
at
➅, the spool shifts to allow fl ow between ➂ and ➁, and between ➃ and ➄.
FEATURES
• Hardened spool and cage for long life.
