A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve which is open in transition, for three-way circuits requiring remote pilot operation.
In neutral (unpiloted), the PD10-50 allows flow from ➂ to ➁ bidirectionally, while flow is blocked from ➂ to ➃. The spring chamber is vented to tank at port ➄, and is inter-nally O-ring sealed from the cartridge flow paths.
On remote pilot signal at ➀, the valve shifts to block flow from ➂ to ➁, while opening flow between ➂ and ➃ bidirectionally. Any pressure at port ➄ is added to the spring value.
• Hardened spool and cage for long life.
• Cost-effective cavity.
