Description
The DBAW40BH1N1X/120-6EG24N9K4E is laid out for a setting range up to 120 bar. Because the pilot spring is matched to that range, the characteristic stays flat even at small settings while the main stage discharges 500 l/min.
Benefits
- Pressure setting range 3.7 to 120 bar for low-pressure circuits
- Matched pilot spring for a flat characteristic curve
- 500 l/min flow in size 40
- Electric unloading through a mounted directional spool valve at 24 VDC
- 12 kg mass, CE conformity, operating pressure of 350 bar maximum
Application
The block appears on power units for conveying equipment, clamping systems and cooling circuits that stay below 120 bar. Unloading takes the pump to zero pressure during pauses and so reduces oil heating.
