Pressure Relief Valve DBW20B2-5X/140-6EG24N9K4E - Bosch Rexroth R901036511
Piping and fittings with a limited pressure rating often set 140 bar as the ceiling. This version covers 4 to 140 bar, discharges up to 400 l/min and weighs 5.36 kg. Adjustment is made on the internal hexagon under the protective cap.

Description
The cylinder does not always dictate the pressure limit, often it is piping, hoses or fittings of an older design. A setting range of 4 to 140 bar keeps the circuit below such limits while the valve discharges the full 400 l/min. The subplate interface follows ISO 6264-08-13.
Benefits
- Setting range 4 to 140 bar, matched to limited line pressure ratings
- Flow up to 400 l/min in size 25
- Pilot-operated poppet valve with spool symbol B and two switching positions
- Internal hexagon with protective cap, subplate mounting to ISO 6264-08-13
- Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
- 5.36 kg mass, NBR seals for HL hydraulic fluid
Application
A typical case is a modernised existing machine whose piping was not replaced and whose pressure rating is therefore fixed. The limited setting range prevents the cut-off pressure from being turned beyond what the line is rated for. The solenoid switches the circuit without changing the stage.
Manufacturer
Bosch Rexroth lists this pressure relief valve DBW20B2-5X/140-6EG24N9K4E under material number R901036511. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Document the pressure rating of piping and fittings before setting the valve.
