The PD12-32 is a screw-in, cartridge style, pilot-operated, spool type, normally closed, hydraulic directional valve
In neutral position the valve blocks flow from port 2 to 3. The spring chamber is internally vented to port 3. On remote pilot signal at port 1, the valve's spool shifts to allow flow from port 2 to 3 unidirectionally. Pressure on port 3 will directly (1:1) affect the pilot pressure required and must be added to the bias spring value
- Hardened spool and cage for long life.
- Industry common cavity.
