PD08-35_sym_2025-10-20

Description

The PD08-35 is a screw-in, cartridge style, pilot-operated, spool type, normally open, hydraulic directional valve.

Operation

In neutral position the valve allows flow from port 2 to 3. The spring bias chamber is internally vented to port 3. On remote pilot signal at port 1, the valve's spool shifts to block flow from port 2 to 3. Pressure on port 3 will directly (1:1) affect the pilot pressure required and must be added to the bias spring value.
