Pressure Relief Valve DBW20B2-5X/140Y6EG24N9K4E - Bosch Rexroth R901208229

In lifting gear, tilting tables and prefill circuits a lot of oil flows while pressure stays comparatively low. This version reproduces exactly that operating case, with a setting range of 4 to 140 bar and flow up to 450 l/min. The subplate interface follows ISO 6264-08-13 and the mass is 5.36 kg.

Benefits

• Setting range 4 to 140 bar for circuits at moderate working pressure
• 450 l/min flow rating, matched to lifting gear and prefill circuits
• Pilot-operated poppet valve in size 25 with spool symbol B
• 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

Technical data

Application

Such a layout is needed on lifting tables, tilting equipment and large cylinders that swallow a lot of volume during rapid traverse. Because the valve discharges the full flow, pressure stays close to the set value when the cylinder reaches its stop. The solenoid switches the circuit without touching the setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/140Y6EG24N9K4E under material number R901208229. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Make sure the return line is sized for 450 l/min, otherwise back pressure falsifies the low pressure stage.
