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.
