Pressure Relief Valve L-DB80F2-3X/25Y - Bosch Rexroth R900948399

The L-DB80F2-3X/25Y limits pressure in low pressure circuits to a value between 5.9 and 25 bar while relieving up to 3600 l/min. It is pilot-operated, uses a poppet seat design and is tied in through a size 80 flange connection. Setting is manual, through an internal hexagon under a protective cap.

Benefits

• 3600 l/min throughput in size 80, laid out for circulation and cooling circuits
• Setting range 5.9 to 25 bar at a maximum operating pressure of 25 bar
• Flange connection with 3 ports, matched to large line cross sections
• Manual setting by internal hexagon under a protective cap, no auxiliary power needed
• Poppet seat design, NBR seals for HL hydraulic fluid, 32 kg

Application

Valves of this kind sit in filter and cooling loops of large power units, in return manifolds and in metallurgical plant. The low setting range protects heat exchangers and filter housings rated for only a few tens of bar. Thanks to the high throughput, back pressure stays low even at full pump delivery.

Manufacturer

Bosch Rexroth, material number R900948399. Size 80 calls for a flange interface, so the line layout should be checked against it before ordering.
