A large power unit passing 7000 l/min needs pressure protection that can dump this flow without building back pressure. The L-DB125F2-3X/16Y limits in poppet seat design to a setting between 5.8 and 16 bar and mounts as a flange valve.

Total price
In low pressure circuits with very large flow the pressure drop across the safety valve decides the efficiency. The pilot operated L-DB125F2-3X/16Y in size 125 takes up to 7000 l/min while holding its setting inside a range of 5.8 to 16 bar.
Benefits
- Up to 7000 l/min maximum flow in size 125, laid out for large circuits at low pressure.
- Poppet seat design, therefore low leakage across the main stage when closed.
- Setting range 5.8 to 16 bar through an internal hexagon with protective cap, secured against accidental adjustment.
- Flange connection with 3 ports plus 2 switching positions, manual actuation available on the valve.
- Electrical connection through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals, 75.05 kg.

Applications
The valve protects large circuits in hydro power plants, paper machines and steel works where several pumps feed one common line. At 7000 l/min the opening curve stays flat enough to keep system pressure from running away while relieving. NBR seals match HL fluid.
