A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
In neutral (unpiloted), the PD10-42 allows flow between 3 and 2 while blocking at 4.
On remote pilot signal at 1, the valve shifts to allow flow between 3 and 4 while blocking at 2.
Since 4 is common to the spring chamber, pressure on 4 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.
