A screw-in, cartridge-style, pilot-operated, 2-position, 4-way, spool-type, hydraulic directional valve.
In the neutral position, the PD12-S61N allows flow between ports ➁ and ➂ and between ports ➃ and ➄. On remote pilot signal at ➀, the valve shifts to allow flow between ports ➂ and ➃, while blocking ports ➁ and ➄The spring chamber is vented to the tank through port ➅. The vented spring chamber allows the valve to be fully pressurized at ports ➀, ➁, ➂, ➃ and ➄ without affecting required pilot pressure. Pressure at ➅ will affect required pilot pressure.
• Hardened spool and cage for long life.
• 110 and 170 psi bias springs available.
