On no remote pilot signal at ① ,the valve allows flow from ③ to ② bi-directionally, while
flow is blocked at ④ ,spring chamber vent-to-atmosphere, which is internally 0-ring
sealed from the cartridge flow paths.
On remote pilot signal at ①， the valve shifts to open from ③ to ④，while blocking
flow at ②．
Because of the vented spring chamber, the cartridge may be fully pressurized at any
port without affecting required pilot pressure.
