Pressure Relief Valve DBW20B2-5X/125-6EG24N9K4E - Bosch Rexroth R901522831

Not every circuit works at the pressure limit, and many cylinders or clamping platens get by on far less. This 4 to 125 bar setting range resolves exactly that band finely, while size 25 still discharges the full 400 l/min. Poppet seat design makes sure the valve closes cleanly even at a low setting.

Benefits

• Setting range 4 to 125 bar with fine resolution for low pressure circuits
• 400 l/min flow despite the low pressure stage, size 25 body
• Pilot-operated poppet valve that seals tightly when closed
• Subplate mounting to ISO 6264-08-13, internal hexagon with protective cap
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.3 kg mass, NBR seals for HL hydraulic fluid

Application

Such a pressure stage is needed in clamping systems with large piston areas, in tilting equipment and in circuits containing plastic components that cannot take high pressure. The maximum operating pressure of the valve remains 350 bar, so pressure peaks elsewhere in the circuit do not endanger the body. The solenoid switches the circuit independently of the pressure setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/125-6EG24N9K4E under material number R901522831. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Pick a version with a wider setting range if the working pressure may later rise above 125 bar.
