Pressure Relief Valve DBW20A2-5X/180-6EG24N9K4E - Bosch Rexroth R901202565

When a valve in an existing machine is replaced, the spool symbol decides whether the circuit diagram still holds. This version carries symbol A and covers a setting range of 4 to 180 bar. The subplate interface follows ISO 6264-08-13 and flow reaches 400 l/min.

Benefits

• Spool symbol A, matched to circuit diagrams that specify it
• Setting range 4 to 180 bar at a maximum operating pressure of 350 bar
• Pilot-operated poppet valve in size 25 rated for up to 400 l/min
• Subplate mounting to ISO 6264-08-13, 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

The typical occasion is replacing an aged relief valve in a power unit running at 180 bar. Because interface and symbol match, the existing subplate and its piping stay in place. After the change, the cut-off pressure has to be set again on the gauge.
