Hydraulic Symbol
Description
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
Operation
In neutral (unpiloted), the valve allows flow passage from port 3 to port 2 bidirectionally, while flow is blocked at port 4. V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge flow paths. On remote pilot signal at port 1, the valve shifts to open from port 3 to port 4, while blocking flow at port 2. Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure.
