PD42-S50 Piloted 3-Way Spool (PD42-S50)
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for three-way circuits requiring remote pilot actuation.
Product Operation
In neutral (unpiloted), the PD42-S50 allows flow from ➂ to ➁ bidirectionally, while flow is blocked at ➃On remote pilot signal at ➀, the valve shifts to open ➂ to ➃ while blocking ➁The spring chamber is vented to the tank through port ➄, which is common to the spring chamber. Pressure on port ➄ will directly (1:1) affect the pilot pressure required and must be added to the bias spring value.
Product Features
• Hardened spool and cage for long life.
• Optional open transition (ports ➁, ➂ and ➃).
