Pressure Relief Valve DBW30B1N5X/210-6EG24N9K4E - Bosch Rexroth R901233370

A power unit rated around 210 bar needs a relief stage whose scale ends in that same band. This pilot-operated pressure relief valve covers 4 to 210 bar, is set at a rotary knob and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 210 bar, so the scale spreads across the usual working band of industrial power units.
• Rotary knob, so the cut-off pressure is found during commissioning without tools.
• Pilot-operated design keeps the set pressure stable up to 580 l/min.
• Seat valve with tight closing, which keeps leakage low while pressure is held.
• Maximum operating pressure of 350 bar above the setting range.
• 6.5 kg weight with solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.

Application

The classic place is pump protection in machine tools, hydraulic power units and test benches rated up to 210 bar. The solenoid drops the circuit to zero pressure during pauses and keeps the HL fluid cooler. The NBR seals suit mineral oil across the usual operating temperature range.
