Directional Spool Valve 4WEH32D6X/6EG110NTS2K4 - Bosch Rexroth R900925710

If pressure in the main circuit drops below the required pilot pressure at times, a valve with internal pilot supply no longer switches reliably. The 4WEH32D6X/6EG110NTS2K4 therefore draws pilot oil externally and returns it internally, at a maximum flow of 1100 l/min.

Benefits

• External pilot oil supply keeps switching independent of the pressure in the main circuit.
• Internal pilot oil return removes the need for a return line.
• Maximum flow of 1100 l/min in size 32 to ISO 4401-10-09-0-05.
• Symbol D with 2 switching positions and 4 ports.
• Solenoid voltage 110 VDC through a connector 3-pole (2 + PE) according to EN 175301-803.
• Operating pressure up to 280 bar at a mass of 35 kg, NBR seals for HL hydraulic fluid.

Applications

The valve is used in presses and power units whose main circuit is unloaded between load phases. Pilot oil then comes from a separate circuit or an accumulator, while the return runs through the tank channel of the subplate. NBR seals are fitted for mineral oil of class HL.
