PD10-50 Valve

SYMBOL:
PD10-50 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, open-in-transition, hydraulic
directional valve for three-way circuits requiring remote pilot actuation.

OPERATION
In neutral (unpiloted), the PD10-50 allows flow from 3 to 2 bidirectionally while flow is
blocked at 4. The spring chamber is vented to tank at port 5, and is internally O-ring
sealed from the cartridge flow paths. On remote pilot signal at 1, the valve shifts to
block flow from 3 to 2, while opening flow between 3 and 4 bidirectionally. Any pressure
at port 5 is added to the spring value.

FEATURES
• Hardened spool and cage for long life.
• Industry common cavity.
