The PD42-S67B is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve.
In the neutral position flow is allowed between ports 2, 3, 4 and 5. On remote pilot signal at port 1 the valve's spool shifts to allow flow between ports 3 and 4, and between ports 2 and 5. On remote signal at port 6 the valve's spool shifts to allow flow between ports 3 and 2, and between ports 4 and 5.
- Hardened spool and cage for long life.
