A cartridge-style 2-way pilot-operated spool-type external-vent directional valve

Technical Feature

OPERATION:
Unpiloted, the valve blocks flow from ③ to ② bidirectionally.V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge flow paths.On remote pilot signal at ① , the valve shifts to open ② to ③ bidirectionally.
Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure.
