Pumpensicherheitsblock DBAW40BF1N1X/100-6EG24N9K4E - Bosch Rexroth R901040450

When a large pump starts, the drive should not have to run up against full system pressure. The DBAW40BF1N1X/100-6EG24N9K4E pump safety block unloads electrically through a built-on directional spool valve and then limits pressure within a range of 3.7 to 100 bar.

Benefits

• Solenoid unloading via a built-on directional spool valve, so the drive starts unloaded.
• Setting range 3.7 to 100 bar at 350 bar maximum operating pressure.
• Up to 500 l/min in size 40 through a flange connection.
• Poppet seat design with a rotary knob for manual setting.
• 24 VDC through a connector, 3-pole (2 + PE) to EN 175301-803, CE conformity, 12.6 kg.

Applications

The block sits directly at the pump outlet of power units with high delivery, for instance in presses and test rigs. The low setting range up to 100 bar suits circuits working below the rated pressure of the series. The limit value is set at commissioning through the rotary knob.
