PD08-35

PILOTED DIRECTIONAL VALVE

Overview

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

Features

  • External vent-to-atmosphere.
  • Range of bias springs available.
  • Sealed spool option for bias spring options 110.
  • Hardened spool and cage for long life.
  • Industry common cavity.
