Pressure Relief Valve L-DB80F2-3X/16XYU - Bosch Rexroth R901071866

In circuits carrying large oil volumes at a low pressure level, the relief stage has to pass the full flow. The L-DB80F2-3X/16XYU is a pilot-operated pressure relief valve built in size 80 for exactly that and handles up to 3600 l/min.

Benefits

• Flow up to 3600 l/min in size 80, sized for wide return cross sections.
• Setting range 3 to 16 bar at 25 bar maximum operating pressure.
• Poppet seat design, tight in the closed condition.
• Internal hexagon with protective cap, so the manual setting is shielded against accidental change.
• Flange connection with 4 ports and a weight of 31.42 kg.

Applications

The valve belongs in low-pressure circuits with heavy circulation, such as cooling and filtration loops, charge pump lines or return sections of large plants. A setting range of 3 to 16 bar covers the back pressure those circuits need. The value is set at commissioning through the internal hexagon under the protective cap.
