PD10-51

PILOTED DIRECTIONAL VALVE

Overview

Description

The PD10-51 is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve

Operation

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