HYPD10-41 (Three Way Pilot Directional Valve)
A cartridge-style 3-way pilot-operated spool-type external-vent directional valve.
Operation:
On no remote pilot signal at ①, the valve allows flow from ③ to ④, while flow is blocked at ②.
On remote pilot signal at ①, the valve shifts to open from ③ to ②, while blocking flow at ④.
Since ④ is common to the spring chamber, pressure on ④ will directly (1:1) affect the pilot pressure required, and must always be added to the bias spring value.
