Pressure Relief Valve DBW20B2-5X/140S6EG24N9K4R12E - Bosch Rexroth R901029506

The DBW20B2-5X/140S6EG24N9K4R12E is the 140 bar step of the DB.10-30 range. The low ceiling protects consumers not rated for higher pressures without cutting the 400 l/min throughput.

Benefits

• Adjustment range 4 to 140 bar for pressure sensitive circuits
• Discharge flow up to 400 l/min in size 25
• Operating pressure permitted to 350 bar at the port
• Pilot-operated seat valve, internal hexagon with protective cap
• Spool symbol B, two switching positions, 24 VDC solenoid actuation
• 4.95 kg weight, NBR seals, CE conformity

Application

Cooling circuits, lubrication loops and mixed pneumatic hydraulic systems often work below 140 bar. If the safety stage is set too high, it responds too late in a failure case. The subplate interface stays compatible with the higher pressure steps of the range.

Manufacturer

Bosch Rexroth lists the valve under material number R901029506. Curves and setting diagrams are in data sheet RE 25802, dimensions and subplates in RE 25802-B.
