Pressure Relief Valve DBW20BG2-5X/180-6EG24N9K4E - Bosch Rexroth R901175591

Clamping and holding circuits need pressure only during the stroke, after which the pump delivers needlessly against the set value. This version unloads through a built-on directional spool valve while protecting the circuit between 3.8 and 180 bar. Threaded connection allows direct installation into the piping, and flow reaches 400 l/min.

Benefits

• Solenoid unloading through a built-on directional spool valve, idling without counter pressure
• Setting range 3.8 to 180 bar at a maximum operating pressure of 350 bar
• Threaded connection with two ports, no subplate needed
• Pressure stage in poppet seat design with internal hexagon and protective cap
• Flow up to 400 l/min in size 25
• 6.92 kg mass, 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803

Application

The version makes sense on clamping stations, assembly machines and equipment that waits several seconds between strokes. Pressureless idling cuts wasted power and spares the pump. Because the valve is piped directly, it also fits power units with no free subplate area.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20BG2-5X/180-6EG24N9K4E under material number R901175591. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. For a retrofit, check that the line cross section suits 400 l/min.
