Directional Spool Valve 4WH16E7X/QM0G24SO746 - Bosch Rexroth R900930870

The task of the valve is reversing oil flows of up to 300 l/min through a hydraulic control signal. Because no solenoids are fitted, the electrical supply is dropped entirely. Operating pressure reaches 280 bar across three switching positions to spool symbol E.

Benefits

• Hydraulic actuation, so no electrical connection at the valve is required
• 300 l/min flow at a maximum operating pressure of 280 bar
• Three switching positions with spool symbol E in size 16
• External pilot oil supply and external return
• 8.54 kg weight, ISO 4401-07-07-0-05 pattern, NBR seals

Application

The valve is used in purely hydraulic control systems, for instance in areas with explosion protection requirements or heavy electrical interference. The control signal comes from an upstream valve. Four ports follow the standard pattern of size 16.

Manufacturer

Bosch Rexroth lists the valve under material number R900930870. The control pressure required is stated in the datasheet for this article.
