Pressure Relief Valve DBW20A2-5X/100-6EG24N9K4R12E - Bosch Rexroth R901204235

A relief valve with too wide a setting range can only be adjusted coarsely at the lower end. The DBW20A2-5X/100-6EG24N9K4R12E is laid out for 4 to 100 bar and limits flows up to 400 l/min within that band.

Benefits

• Setting range 4 to 100 bar, suited to sub-circuits below plant pressure.
• Up to 400 l/min in size 25 at 350 bar maximum operating pressure.
• Electrical unloading at 24 VDC across 2 switching positions.
• Pilot-operated seat valve with internal hexagon and protective cap.
• CE conformity, 5.38 kg, subplate mounting to ISO 6264-08-13.

Applications

The valve protects sub-circuits working at a lower pressure than the main supply, such as clamping, cooling or feed lines. Through the solenoid the circuit can be unloaded electrically without stopping the pump. The value set is entered through the internal hexagon and secured by the protective cap.
