Pressure Relief Valve DBW20A2-5X/280Y6EG24N9K4E - Bosch Rexroth R900786517

The DBW20A2-5X/280Y6EG24N9K4E is the spool symbol A version in size 25. It limits pressure across 4 to 280 bar, passes 450 l/min and holds 350 bar maximum operating pressure. The setting is made through an internal hexagon under a protective cap and unloading runs on 24 VDC.

Benefits

• Spool symbol A, a direct replacement for identically coded valves in service
• Setting range 4 to 280 bar at 450 l/min flow
• Pilot-operated poppet valve, subplate mounting to ISO 6264-08-13, 2 ports
• Solenoid actuation on 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• NBR seals matched to HL hydraulic fluid, 5.59 kg

Application

The valve protects power units running around 280 bar, for example in presses and hydraulic clamping systems. Since the symbol defines the switching function of the unloading stage, it has to agree with the circuit diagram during a swap. Pipework and subplate stay as they are.
