Pressure Relief Valve L-DB125F2-3X/16Y - Bosch Rexroth R900512403

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.
