Pressure Relief Valve DB52F1-3X/315UV - Bosch Rexroth R901400322

When the relief setting has to be corrected during operation, a rotary knob is quicker than a tool. The pilot-operated pressure relief valve DB52F1-3X/315UV is set that way, covers 3.9 to 315 bar and carries up to 2000 l/min through the size 52 flange connection.

Benefits

• Adjustment range of 3.9 to 315 bar at the rotary knob, no tool needed.
• Flow up to 2000 l/min at the flange connection of size 52.
• Poppet seat design, pilot-operated, with two ports and two switching positions.
• FKM seals for operation on HL fluid at raised temperature.
• 27.09 kg in weight, wired through a 3-pole connector (2 + PE) to EN 175301-803.

Applications

The valve protects the pump circuit of large power units, for example on presses, rolling mills and hydro power plants. Because it works as a poppet, leakage in the closed state stays low. The rotary knob allows the pressure stage to be corrected during commissioning.
