The PD12-S62 is a screw-in, cartridge style, pilot operated, spool-type, normally closed, hydraulic directional valve
In the neutral position flow is allowed between ports 2 and 3 and between ports 4 and 5 bidirectionally. On remote pilot signal at port 1 the valve's spool shifts to block flow at all ports, the spring chamber is vented to the tank through port 6. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, 4, and 5 without affecting required pilot pressure. Pressure at port 6 will affect required pilot pressure
- Hardened spool and cage for long life.
- Optional sealed spool between ports 1 and 2.
- Choice of two bias spring values.
- Vented spring chamber.
