Pressure Relief Valve DBW20BG2-5X/315-6EG24N9K4E - Bosch Rexroth R901075704

High pressure units also stand still between strokes, and idling against 315 bar then costs a particularly large amount of power. This version therefore combines poppet seat pressure limitation with solenoid unloading through a built-on directional spool valve. Threaded connection allows direct installation, and flow reaches 400 l/min.

Benefits

• Solenoid unloading through a built-on directional spool valve, also in high pressure circuits
• Setting range 3.8 to 315 bar at a maximum operating pressure of 350 bar
• Threaded connection with two ports, no subplate required
• Pressure stage in poppet seat design with internal hexagon and protective cap
• Flow up to 400 l/min in size 25
• 6.9 kg mass, 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803

Technical data

Application

The version is needed in presses and clamping units of the 315 bar class that wait between working strokes. The higher the system pressure, the greater the benefit of unloading, because wasted power rises with pressure. Direct threaded connection saves the subplate and the space it would take.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20BG2-5X/315-6EG24N9K4E under material number R901075704. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. After piping, check the pressure that has been set on a gauge.
