Pressure Relief Valve DBW20B1-5X/200-6EG24N9K4E - Bosch Rexroth R901183891

At 200 bar system pressure the standard rating of 400 l/min is enough for most power units, while the rotary knob allows adjustment by hand. This version combines both and covers a setting range of 4 to 200 bar. The subplate interface follows ISO 6264-08-13 and the mass is 5.44 kg.

Benefits

Technical data

Application

The target is power units in fixture building and assembly technology whose clamping pressure lies between 100 and 200 bar depending on the part. The operator sets the value on the knob without opening a cover. The solenoid switches the circuit without moving the knob position.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B1-5X/200-6EG24N9K4E under material number R901183891. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. A pressure gauge directly on the power unit makes setting and later checking easier.
