Pressure Relief Valve L-DB150F2-3X/16Y - Bosch Rexroth R900383360

Where a pump group delivers several thousand litres per minute, the size of the relief valve decides the back pressure in the return line. The L-DB150F2-3X/16Y accepts up to 13000 l/min and holds pressure inside a set window of 5.8 to 16 bar.

Benefits

• Adjustment range 5.8 to 16 bar - the higher lower limit compared with the 3 bar version of the same series.
• 13000 l/min flow in size 150 at a maximum operating pressure of 25 bar.
• Pilot-operated poppet valve with two switching positions and three ports.
• Flange connection type 21 to EN 1092-2, fitted straight into large pipework.
• Adjustment through an internal hexagon under a protective cap, which can be sealed against changes in service.

Application

Typical applications are cooling and circulation loops, hydropower installations and large press power units with low system pressure and very high throughput. Hydraulic fluid is HL and sealing is NBR. Because of the 107 kg weight, the installation point should stay accessible to lifting gear.
