Pressure Relief Valve DBW20B2-5X/65-6EG24N9K4E - Bosch Rexroth R901158767

A circuit that may only take a few dozen bar needs a valve with a correspondingly soft spring, otherwise the cut-off point cannot be hit cleanly. This setting range of 4 to 65 bar resolves exactly that section. Flow capacity remains fully intact at up to 400 l/min, and the subplate interface follows ISO 6264-08-13.

Benefits

• Setting range 4 to 65 bar for preload, flushing and lubrication circuits
• Flow up to 400 l/min despite the low pressure stage
• Body still released for 350 bar operating pressure
• 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
• 4.95 kg mass, NBR seals for HL hydraulic fluid

Application

Such a stage is needed for accumulator preload circuits, for the flushing loop of a closed circuit and for lubrication lines with limited pressure. Because the body is still released for 350 bar, the valve survives being connected to a high pressure branch by mistake. The solenoid switches the circuit independently of the setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/65-6EG24N9K4E under material number R901158767. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. At settings this low, back pressure in the return line carries a lot of weight, so size that line generously.
