Pressure Relief Valve L-DB100F2-3X/25XY - Bosch Rexroth R900753397

Return and back pressure lines in large plant carry enormous oil volumes at comparatively modest pressure. The L-DB100F2-3X/25XY is built for that duty and relieves up to 6000 l/min in size 100, limited to 7 to 25 bar.

Benefits

• 6000 l/min maximum flow in size 100.
• Pressure adjustment range 7 to 25 bar, operating pressure up to 25 bar.
• Flange connection with 4 ports, no pipe fitting in the main stream.
• Pilot-operated poppet seat design closes tightly at rest.
• Manual pressure adjustment through an internal hexagon with protective cap.
• NBR seals for HL hydraulic fluid, mass 50 kg.

Applications

The valve protects low pressure circuits in hydro power plant, rolling mills and large test rigs and holds back pressure in the return line. Because the setting is made by hand, the value is kept without auxiliary power. NBR seals are fitted for mineral oil of class HL.
