A cartridge-style, pilot-operated, spool-type, normally open, hydraulic directional valve

Technical Feature

OPERATION:
In neutral position(unpiloted), the valve allows flow from port ③ to ② bidirectionally.The spring chamber is vented to atmosphere which is internally O-ring sealed from the cartridge flow paths. On remote pilot signal at port ①, the valve's spool shifts to block flow from port ③ to ② bidirectionally. Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure.
