Pressure Relief Valve DBW20B2-5X/300-6EG24N9K4E - Bosch Rexroth R901016100

A figure of 300 bar is often used in hydraulic diagrams as a round design limit, because it leaves reserve to the 350 bar limit of the frame size. This version covers exactly that band from 4 to 300 bar. The pilot-operated poppet valve takes up to 400 l/min across the ISO 6264-08-13 subplate interface and weighs 5.4 kg.

Benefits

• Setting range 4 to 300 bar with reserve to the 350 bar operating pressure
• Flow up to 400 l/min in size 25
• Pilot-operated poppet valve with spool symbol B and two ports
• 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
• 5.4 kg mass, NBR seals for HL hydraulic fluid

Application

The stage is used in presses, forging equipment and hydraulic drives designed for 300 bar. The remaining margin to the body limit absorbs pressure peaks from fast load changes. The solenoid switches the circuit from the control system without touching the pressure setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/300-6EG24N9K4E under material number R901016100. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. After any maintenance on the circuit, check that the cut-off pressure still sits at 300 bar.
