Pressure Relief Valve DBW30B1N5X/210Y6EG24N9K4E - Bosch Rexroth R900775074

Central power units with high delivery often run at a rated pressure around 210 bar and still need to be adjustable. This pilot-operated pressure relief valve covers 4 to 210 bar at the rotary knob and accepts up to 700 l/min.

Benefits

• 700 l/min permitted flow with a setting range of 4 to 210 bar.
• Rotary knob, so the cut-off pressure can be trimmed at the machine without tools.
• Pilot-operated seat valve holds pressure across the full flow range.
• Maximum operating pressure of 350 bar above the setting range.
• Electrical unloading at 24 VDC across two switching positions.
• 6.6 kg weight with connection diagram ISO 6264-10-17.

Technical data

Application

A fit for central hydraulic supplies, presses and forming lines feeding several consumers. The rotary knob allows the system pressure to be matched to changing processes. During waiting times the solenoid drops the circuit to zero pressure, relieving the pump and the HL hydraulic fluid.
