PD10-45 Piloted 2-Way Spool (PD10-45)
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for two-way circuits requiring remote pilot actuation and vented spring chamber.
Product Operation
In neutral (unpiloted), the PD10-45 allows flow from ➂ to ➁ bidirectionally. The spring chamber is directed to port ➃On remote pilot signal at ➀, the valve shifts to block from ➂ to ➁, bidirectionally.Since ➃ is common to the spring chamber, pressure on ➃ will directly (1:1) affect the pilot pressure required, and must always be added to the bias spring value.
Product Features
• Hardened spool and cage for long life.• Industry common cavity.
