DIRECTIONAL VALVES

PD10-32 Piloted 2-Way Spool, Normally Closed,

DESCRIPTION

A screw-in, cartridge-style, pilot-operated, spool-type, normally closed, hydraulic

directional valve for two-way circuits requiring remote pilot actuation.

OPERATION

In neutral (unpiloted), the PD10-32 blocks ﬂ ow from ➂ to ➁ bidirectionally.

The spring bias chamber is internally vented to

➂.

On remote pilot signal at

➀, the valve shifts to open ➁ to ➂ unidirectionally.

FEATURES

• Hardened spool and cage for long life.

• Industry common cavity.
