Directional Spool Valve H-4WEH25H6X/6EG24N9TK4/B15 - Bosch Rexroth R900932391

This directional valve controls flows of up to 700 l/min at a maximum operating pressure of 350 bar. Spool symbol H shapes the centre position, pilot oil supply comes from outside and the return runs internally. Four ports sit on the ISO 4401-08-08-0-05 pattern.

Benefits

• Spool symbol H with three switching positions and internal pilot oil return
• 700 l/min flow, 350 bar maximum operating pressure
• Size 25 with four ports to ISO 4401-08-08-0-05
• Solenoid actuation at 24 V DC, connector 3-pole (2 + PE) according to EN 175301-803
• 17.7 kg weight, NBR seals, HL hydraulic fluid

Application

The valve is used in large power units whose actuators must show defined behaviour when the solenoids drop out. External pilot supply keeps the pilot stage ready even when working pressure falls. The internal return saves a line to tank.
