Pressure Relief Valve DBW20B1-5X/250Y6EG24N9K4E - Bosch Rexroth R901514017
The rotary knob on this version allows the pressure to be set by hand, without reaching for a tool. The range runs from 4 to 250 bar and flow reaches 450 l/min. At 6.6 kg the valve is somewhat heavier than the versions with an internal hexagon.

Description
On test rigs and experimental setups the cut-off pressure often changes several times a day, and a rotary knob is quicker than an internal hexagon. This version covers 4 to 250 bar and discharges up to 450 l/min. The subplate interface follows ISO 6264-08-13 and the valve weighs 6.6 kg.
Benefits
- Rotary knob for setting the pressure by hand, no tool needed at the valve
- Setting range 4 to 250 bar at a maximum operating pressure of 350 bar
- Flow up to 450 l/min across the ISO 6264-08-13 subplate interface
- Pilot-operated poppet valve in size 25 with spool symbol B
- Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
- 6.6 kg mass, NBR seals for HL hydraulic fluid
Application
The knob pays off wherever pressure is part of the daily routine, on test benches, during commissioning and at tool changes with varying clamping pressure. The 450 l/min rating of size 25 also covers larger pumps. The solenoid switches the circuit independently of the pressure stage that has been set.
Manufacturer
Bosch Rexroth lists this pressure relief valve DBW20B1-5X/250Y6EG24N9K4E under material number R901514017. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Where the pressure should stay fixed after commissioning, a version with internal hexagon and protective cap is the quieter choice.
