Pressure Relief Valve DBW20A2-5X/280-6EG24N9K4E - Bosch Rexroth R901194699

Forming and press circuits often work at 280 bar, because force and component size balance out there. This version covers 4 to 280 bar and carries spool symbol A. The pilot-operated poppet valve takes up to 400 l/min and mounts on a subplate to ISO 6264-08-13.

Benefits

• Setting range 4 to 280 bar for forming and press circuits
• Spool symbol A, two switching positions and two ports
• Flow up to 400 l/min in size 25
• Internal hexagon with protective cap, subplate mounting to ISO 6264-08-13
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.36 kg mass, NBR seals for HL hydraulic fluid

Application

The field of use covers presses and punching machines whose cylinders are rated at 280 bar. The margin to the permissible 350 bar absorbs short pressure peaks from the forming stroke. The solenoid switches the circuit without changing the value that was set.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20A2-5X/280-6EG24N9K4E under material number R901194699. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. With fast forming cycles it pays to record the pressure trace, so the cut-off point is not hit again and again.
