Product Information DIRECTIONAL VALVE Piloted 3-Way Spool, Vent-to-air Type:PD16-2340-35 Operating pressure: 350 bar (5000 psi) Proof pressure: 630 bar (9000 psi) Flow: 175 L/min Description A screw-in, cartridge-style, pilot-operated, spool-type, vent-to-air, hydraulic directional valve for 3-way circuits requiring remote pilot actuation. In neutral (unpiloted), the PD16-2340-35 allows flow from ③ to ② bidirectionally, while flow is blocked at ④ . The spring chamber vent-to-air, which is internally O-ring sealed from the cartridge flow paths. On remote pilot signal at ① ,the valve shifts to open from ③ to ④ ,while blocking flow at ② . Since spring chamber vent-to-air and O-ring sealed, the cartridge may be fully pressurized at any port without affecting required pilot pressure, the pilot pressure would not be affected by the pressure from ④ . Technical Data Proof pressure Oil volume required to full shift Internal leakage Installation torque Pilot pressure required For 35.5 bar (515 psi) spring: 35.5 bar (515 psi) to full spool shift Temperature range -40℃ ~ 120℃ with standard buna seals -26℃ ~ 204℃ with fluorocarbon seals Mineral based or synthetics with lubricating properties at viscosities of 7.4~420cSt (50-2000ssu) Pressure drop (bar/psi) Operating pressure Cavity tool
