PD10-41

PILOTED DIRECTIONAL VALVE

Overview

Description

The pd10-41xx is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve.

Operation

In neutral position the valve allows flow from port 3 to 4, while port 2 is blocked. On remote pilot signal at port 1 the valve shifts to open from 3 to 2, while blocking flow to port 4. Since port 4 is common to the spring chamber, pressure on port 4 will directly (1:1) affect the pilot pressure required and must be added to the bias spring value.

Features

  • Hardened spool and cage for long life.
  • Industry common cavity.
