Hydraforce PD10-40-0-NS-110 Piloted 3-Way Valve
The pd10-40xx is a screw-in, cartridge style, pilot-operated, spool type, hydraulic directional valve. Description The pd10-40xx is a screw-in, cartridge style, pilot-operated, spool type, hydraulic directional valve. Operation In neutral position the valve allows flow from port 3 to 2 bidirectionally, while port 4 is blocked. The spring chamber is vented to atmosphere "v" which is internally o-ring sealed from the cartridge flow paths. On remote pilot signal at port 1, the valve's spool shifts to open port 3 to 4 while port 2 is blocked. Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure. Features Hardened spool and cage for long life. Industry common cavity.
