PD42-S60N

PILOTED DIRECTIONAL VALVE

Overview

Description

The PD42-S60N is a screw-in, cartridge style, pilot operated, spool-type, hydraulic directional valve

Operation

In the neutral position flow is allowed between ports 2 and 3 and between ports 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. The spring chamber is vented to the tank through port 6. The vented spring chamber allows the valve to be fully pressurized at ports 2, 3 and 4 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.
