PD42-S50 Valve

SYMBOL:
PD42-S50 Valve symbol

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 PD42-S50 allows flow from 3 to 2 bidirectionally while flow
is blocked at 4. On remote pilot signal at 1, the valve shifts to allow flow between
3 and 4 while blocking at 2. The spring chamber is vented to the tank through port 5.
Pressure at 5 will directly (1:1) affect required pilot pressure and must be added to
the spring value.

FEATURES
• Hardened spool and cage for long life.
• Optional open transition for ports 2, 3 and 4.
