Pressure Relief Valve DBW20B2-5X/350-6EG24N9K4E - Bosch Rexroth R901380610

When a machine uses the full permissible pressure of its frame size, the relief valve has to be adjustable that far as well. This version covers 4 to 350 bar and so reaches the maximum operating pressure of 350 bar. The pilot-operated poppet valve discharges up to 400 l/min across the ISO 6264-08-13 subplate interface.

Benefits

• Setting range 4 to 350 bar, matching the maximum operating pressure
• Pilot-operated poppet valve in size 25 rated for up to 400 l/min
• Internal hexagon with protective cap for a permanently fixed pressure stage
• Spool symbol B, two switching positions, two ports
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.38 kg mass, NBR seals for HL hydraulic fluid

Application

This pressure stage is called for in forging presses, high pressure clamping systems and test rigs that exploit the permissible pressure of the frame size. Since the range extends to the body limit, the cut-off pressure should be matched carefully to the weakest component in the circuit. The solenoid switches the circuit from the control system.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/350-6EG24N9K4E under material number R901380610. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Before setting the valve, check which component in the circuit dictates the tightest pressure limit.
