DESCRIPTION

A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for

three-way circuits requiring remote pilot actuation.

OPERATION

In neutral (unpiloted), the PD10-41 allows ﬂ ow from ➂ to ➃. ➁ is blocked.

On remote pilot signal at

➀, the valve shifts to open from ➂ to ➁, while blocking

ﬂ ow to

➃.

Since

➃ is common to the spring chamber, pressure on ➃ will directly (1:1) affect the

pilot pressure required, and must always be added to the bias spring value.

Note: Consult factory for applications where bi-directional ﬂ ow is required when the

valve is in the normal or spring-offset position.

FEATURES

• Hardened spool and cage for long life.

• Industry common cavity.
