Directional Spool Valve H-4WH25E6X/S2SO6 - Bosch Rexroth R900956607

A size 25 spool carrying 700 l/min can no longer be shifted directly by a solenoid. This hydraulically actuated valve uses a pilot pressure instead and switches three positions to symbol E at a maximum operating pressure of 350 bar.

Benefits

• 700 l/min through interface ISO 4401-08-08-0-05, size 25
• Hydraulic actuation with external pilot oil supply and external return
• Symbol E with three switching positions and four ports
• Maximum operating pressure 350 bar, NBR seals
• Subplate mounting, weight 17.44 kg

Application

The valve controls main rams in large presses, forging plant and test rigs. The external pilot circuit allows a separate control pressure, independent of the main gallery. In mid position symbol E links the ports so the load stands unloaded.

Manufacturer

Bosch Rexroth lists the valve under material number R900956607. Data sheet RE 24751 describes the pilot operated directional spool valves of this series.
