PD10-42 Piloted 3-Way Spool, Internal Vent (PD10-42)
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 PD10-42 allows flow from ➂ to ➁ bidirectionally while ➃ is blocked.
On remote pilot signal at ➀, the valve shifts to open from ➂ to ➃, while blocking flow at ➁Since 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 piloted position.
Product Features
• Hardened spool and cage for long life.• Industry common cavity.
