Pressure Relief Valve L-DB125F2-3X/16XY - Bosch Rexroth R900342963

As soon as the relief setting has to be switched remotely, the plain Y version is no longer enough. The L-DB125F2-3X/16XY therefore takes pilot oil out through a port of its own, works with 4 ports and limits flows up to 7000 l/min to a setting between 5.8 and 16 bar.

Benefits

• Separate pilot port in addition to the drain allows remote adjustment as well as unloaded circulation.
• 4 ports with 2 switching positions, flange connection in size 125.
• Maximum flow 7000 l/min, setting range 5.8 to 16 bar in poppet seat design.
• Manual actuation on the valve, 3-pole connector (2 + PE) to EN 175301-803.
• NBR seals for HL fluid, weight 82 kg.

Applications

The valve serves large installations whose pumps alternate between working pressure and unloaded circulation, for example locks, presses and cooling water circuits. Through the extra pilot port a second pressure level can be preset, alternatively the valve can be fully relieved. At 82 kg a lifting aid is required during assembly.
