Pressure Relief Valve DBW30B2N5X/350Y6EG24N9K4E - Bosch Rexroth R900776670

Large pump groups in the upper pressure band ask both things of their relief stage at once. This pilot-operated pressure relief valve covers 4 to 350 bar and accepts up to 700 l/min.

Benefits

• Setting range of 4 to 350 bar, reaching the maximum operating pressure of the valve.
• 700 l/min permitted flow for circuits with several pumps or accumulator discharge.
• Internal hexagon under a protective cap keeps the high setting secure.
• Pilot-operated seat valve that holds pressure tightly.
• Electrical unloading at 24 VDC across two switching positions.
• 6.52 kg weight with connection diagram ISO 6264-10-17.

Application

Meant for presses, forging lines and central hydraulic supplies where the full pump flow passes across the relief stage during a fault. The concealed adjustment holds the approved value. The solenoid runs the system pressureless during setup pauses, with approval for HL hydraulic fluid.
