Pressure Relief Valve DBW30B1N5X/350-6EG24N9K4E - Bosch Rexroth R901172450

If a circuit is to use the full permitted pressure of size 32, the relief stage has to be adjustable that far as well. This pilot-operated pressure relief valve covers 4 to 350 bar and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 350 bar, ending at the maximum operating pressure of the valve.
• Rotary knob, so the cut-off point is found during run-in without tools.
• Pilot-operated seat valve design holds pressure across the whole flow range up to 580 l/min.
• Electrical unloading at 24 VDC across two switching positions.
• Connection diagram ISO 6264-10-17 for standard subplates.
• 6.62 kg weight at 580 l/min maximum flow.

Application

Meant for presses, test benches and clamping systems that use the full pressure range of the size. The rotary knob allows the cut-off pressure to be matched to new tooling. The solenoid drops the system to zero pressure during pauses, and the NBR seals with HL fluid approval suit mineral oil installations.
