PILOTED DIRECTIONAL VALVE
Overview
Symbol
Description
The PD12-S62 is a screw-in, cartridge style, pilot operated, spool-type,
normally closed, hydraulic directional valve
Operation
In the neutral position flow is allowed between ports 2 and 3 and
between ports 4 and 5 bidirectionally. On remote pilot signal at port 1 the
valve's spool shifts to block flow at all ports, 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.
❍
Choice of two bias spring values.
❍
Vented spring chamber.
