HYPD10-34 (Two Way Pilot Directional Valve, Normally Closed)
A cartridge-style 2-way pilot-operated spool-type external-vent directional valve.
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.
