Directional Spool Valve H-4WEH25HP6X/6EG24N9S2K4 - Bosch Rexroth R901052457

Large cylinders in presses and lifting gear call for flows that require a pilot stage. The H-4WEH25HP6X/6EG24N9S2K4 is a pilot operated size 25 spool valve for up to 700 l/min at 350 bar, switched by a 24 V DC solenoid.

Benefits

• 700 l/min flow through the size 25 interface to ISO 4401-08-08-0-05.
• 350 bar maximum operating pressure in the pilot operated design.
• Spool symbol P across three switching positions, with four ports for the main circuit.
• External pilot oil supply and external return, so pilot pressure is routed independently of the main circuit.
• 24 V DC at the 3-pole connector (2 + PE), at a valve weight of 20.34 kg.

Application

It is used in power units with large differential cylinders, for example in presses, injection moulding machines and hydraulic works. The external pilot supply also suits circuits in which main pressure fluctuates strongly.

Manufacturer

Bosch Rexroth assigns the valve to product family H-4W.H.. . The factory designation is Bosch Rexroth material number R901052457. Characteristic curves, pilot pressures and installation dimensions are given in data sheet RE 24751, with RE 07600-B as a supplement.
