A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
In neutral (unpiloted), the PD10-44 blocks flow from ➂ to ➁ bidirectionally. The spring chamber is directed to port ➃, which is internally O-ring sealed from the cartridge flow paths.
On remote pilot signal at ➀, the valve shifts to open from ➁ to ➂, bidirectionally.Any pressure on port ➃ is added to the spring value.
• Hardened spool and cage for long life.
• Industry common cavity.
