Technical Feature
OPERATION：
In neutral position(unpiloted), the valve allows flow from port ③ to ② bidirectionally, while
port ④ is blocked. 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 open port ③ to ④ ,while port
② is blocked.
Because of the vented spring chamber, the cartridge may be fully pressurized at any port
without affecting required pilot pressure.
