Every pump circuit needs pressure protection that can carry the full flow in a fault. The DBW20B2-5X/315-6EG24N9K4/12SO631=CSA does that at up to 500 l/min, with an adjustment range of 4 to 315 bar and a maximum operating pressure of 350 bar.
Benefits
- 500 l/min relief flow through the port to ISO 6264-08-13.
- Adjustment range 4 to 315 bar, set through the internal hexagon with protective cap.
- Electrical unloading through the solenoid on 24 V DC.
- Poppet design in the pilot stage, which gives tight closing at rest.
- 5.3 kg weight with NBR seals for HL hydraulic fluid.
