  • 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.
