PD12-35 Valve

PD12-32 Valve symbol

A screw-in, cartridge-style, pilot-operated, spool-type, normally-closed
hydraulic directional valve for two-way circuits requiring remote pilot actuation.

In neutral (unpiloted), the PD12-35 allows flow from 2 to 3. The spring bias chamber
is internally vented to 3. On remote pilot signal at 1, the valve shifts to block flow
between 2 and 3.
Note: Back pressure at 3 will increase the pilot pressure required at 1 to shift, at a
ratio of 1:1. 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.
