Pressure Relief Valve DBW30B2N5X/315-6EG24N9K4E - Bosch Rexroth R901078442

In the upper pressure band the cut-off value is part of the machine documentation. This pilot-operated pressure relief valve is set from 4 to 315 bar through an internal hexagon under a protective cap and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 315 bar, secured under the protective cap.
• Maximum operating pressure of 350 bar, keeping a margin above the top setting.
• Pilot-operated seat valve that holds high pressure tightly.
• The set pressure stays stable across the flow range up to 580 l/min.
• Electrical unloading at 24 VDC across two switching positions.
• 6.56 kg weight with connection diagram ISO 6264-10-17.

Application

Intended for presses, test benches and clamping systems in the upper pressure band whose relief setting is tested and recorded. The concealed adjustment ensures the recorded value stays intact. The solenoid unloads the circuit during pauses and spares the pump.
