PD16-S63

PILOTED DIRECTIONAL VALVE

Overview

Description

The PD16-S63 is a screw-in, cartridge style, pilot operated, spool-type, hydraulic directional valve

Operation

In the neutral position all ports are blocked. On remote pilot signal at port 1 the valve's spool shifts to allow flow between ports 2 and 3, and 4 and 5. The spring chamber is vented to the tank through port 6. The vented spring chamber allows the valve to be fully pressurized at ports 1, 2, 3, 4, and 5 without affecting required pilot pressure. Pressure at port 6 will affect required pilot pressure

Features

  • Hardened spool and cage for long life.
  • Optional sealed spool between ports 1 and 2.
