Pressure Relief Valve DBW30B2N5X/200US6EG24N9K4R12 - Bosch Rexroth R901024352

Running a valve with a 315 bar spring in a 180 bar circuit puts the working point at the bottom of the scale. The DBW30B2N5X/200US6EG24N9K4R12 instead offers an adjustment range of 2 to 200 bar and uses its travel across the whole working range of the plant.

Benefits

• Adjustment range 2 to 200 bar, matched to medium pressure circuits.
• 650 l/min flow in size 32, operating pressure permitted up to 350 bar.
• Pilot-operated seat valve with an internal hexagon and protective cap against unauthorised adjustment.
• Subplate mounting to ISO 6264-10-17 with two ports and two switching positions.
• 7.1 kg, solenoid actuation on 24 VDC, connector 3-pole (2 + PE) to EN 175301-803.

Applications

It is installed in the pressure line of power units for clamping hydraulics, lift tables and conveying plant. An adjustment range up to 200 bar fits systems whose cylinder sizing stays below that figure anyway. The permitted 350 bar operating pressure leaves headroom for spikes during reversal.
