Pressure Relief Valve DBW20A2-5X/280-6EG24NK4E - Bosch Rexroth R900773267

Changing tools and recipes call for different system pressures from one and the same plant. The DBW20A2-5X/280-6EG24NK4E covers that span with a setting range of 4 to 280 bar while limiting flows up to 400 l/min.

Benefits

• Setting range 4 to 280 bar, one frame size for different operating points.
• Up to 400 l/min at 350 bar maximum operating pressure.
• Pilot-operated seat valve with internal hexagon and protective cap against accidental change.
• Electrical unloading through the solenoid at 24 VDC.
• CE conformity, 5.38 kg, subplate mounting to ISO 6264-08-13 in size 25.

Applications

The valve is used on power units of presses, clamping systems and test rigs whose operating pressure is fixed per job. Electrical unloading allows pressure-free circulation during pauses without stopping the drive. HL hydraulic fluid and NBR seals are foreseen for operation.
