PD42-M40 Piloted 3-Way Spool, External Vent (PD42-M40)
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
Product Operation
In neutral (unpiloted), the PD42-M40 allows flow passage from ➂ to ➁ bidirectionally, while flow is blocked at ➃. V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge flow paths.
On remote pilot signal at ➀, the valve shifts to open from ➂ to ➃, while blocking flow at ➁The vented spring chamber allows PD42-M40 to be fully pressurized at any port
without affecting required pilot pressure.
Product Features
• Hardened spool and cage for long life.
• Optional sealed pilot.
• Industry-standard ISO cavity.
