PD16-S67D

PILOTED DIRECTIONAL VALVE

Overview

Description

The PD16-S67D is a screw-in, cartridge style, pilot operated, spool-type, hydraulic directional valve.

Operation

In the neutral position flow is allowed between ports 2, 4 and 5. On remote pilot signal at port 1 the valve's spool shifts to allow flow between ports 3 and 4, and between ports 2 and 5. On remote pilot signal at port 6 the valve's spool shifts to allow flow between ports 3 and 2, and between ports 4 and 5.

Features

  • Hardened spool and cage for long life.
  • 110 and 170 psi bias springs available.
