PD10-34

PILOTED DIRECTIONAL VALVE

Overview

Description

The PD10-34 is a screw-in, cartridge style, pilot operated, spool-type, normally closed hydraulic directional valve

Operation

In neutral position the valve blocks flow from port 2 to 3. The spring chamber is vented to atmosphere "v" which is internally o-ring sealed from the cartridge flow paths. On remote pilot signal at port 1, the valve's spool shifts to allow flow from port 2 to 3 bidirectionally. Because of the vented spring chamber, the cartridge may be fully pressurized at any port without affecting required pilot pressure

Features

  • External vent-to-atmosphere.
  • Range of bias springs available.
  • Sealed spool option for bias spring options 110, 130 and 170.
  • Hardened spool and cage for long life.
  • Industry common cavity.
