The PD10-44 is a screw-in, cartridge style, pilot-operated, spool type, hydraulic directional valve
In neutral position the valve blocks flow from port 2 to 3. On remote pilot signal at port 1, the valve's spool shifts to allow flow from port 2 to 3 bidirectionally. The spring chamber is vented to port 4 which is internally o-ring sealed from the cartridge flow paths. Pressure on port 4 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.
