The PD16-S67C is a screw-in, cartridge style, pilot operated, spool-type, hydraulic directional valve.
In the neutral position all ports are blocked. 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 pilot 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. Optional sealed spool between ports 1 and 2.
