A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
In neutral (unpiloted), the PD10-41 allows flow from ➂ to ➃. ➁ is blocked.On remote pilot signal at ➀, the valve shifts to open from ➂ to ➁, while blocking flow to ➃Since 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.
Note: Consult factory for applications where bi-directional flow is required when the
valve is in the normal or spring-offset position.
• Hardened spool and cage for long life.• Industry common cavity.
