The PD42-M45 is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve
In neutral position the valve allows flow from port 2 to 3, bidirectionally. On remote pilot signal at port 1, the valve's spool shifts to block flow from port 2 to 3. 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
- Rated for 345 bar (5000 psi) operating pressure (polyurethane seals required).
- Hardened spool and cage for long life.
- Optional sealed pilot
- Industry-common ISO cavity.
