Pumpensicherheitsblock DBAW40BF2N1X/100S6EG24N9K4QMBG24R12 - Bosch Rexroth R901512223

Protecting a pump against overload while still starting it unloaded takes both functions in one block. The DBAW40BF2N1X/100S6EG24N9K4QMBG24R12 limits pressure across a 3.7 to 100 bar setting range and unloads the pump through a built-on directional spool valve. The pilot-operated poppet seat section handles up to 650 l/min at a maximum operating pressure of 350 bar, and the size 40 flange connection carries 14 kg of valve weight.

Benefits

• Pressure setting range 3.7 to 100 bar via internal hexagon with protective cap
• Flow up to 650 l/min in size 40
• Maximum operating pressure 350 bar at the flange connection
• Solenoid unloading on 24 VDC, 2 switching positions, 2 ports
• Pilot-operated relief section in poppet seat design, spool symbol B, NBR seals
• Weight 14 kg, wiring through a 3-pole connector (2 + PE) to EN 175301-803

Applications

The block mounts straight onto the pump outlet and takes over relief duty for the whole circuit. During start-up the solenoid routes flow to tank without pressure, so the drive runs up free of load torque. Set the 3.7 to 100 bar range to the working pressure of the machine rather than to the 350 bar ceiling.
