Pressure Relief Valve DBW20B2-5X/100S6SMG24N9K4B12E - Bosch Rexroth R901171794

A response pressure just above the working pressure keeps power losses small. This pilot-operated size 25 valve is set to a value between 4 and 100 bar and discharges a flow of up to 400 l/min.

Benefits

• Pressure setting range of 4 to 100 bar, suited to circuits with a low working pressure
• Flow of up to 400 l/min, the permitted operating pressure is 350 bar
• Electrical unloading on 24 VDC in two switching positions
• Internal hexagon with protective cap, so the setting stays secured against changes
• Subplate mounting ISO 6264-08-13, NBR seals and a mass of 6.18 kg

Applications

The valve is used in power units for conveying equipment, clamping fixtures and cooling circuits at a low pressure level. The unloading solenoid takes pressure off the pump during pauses. HL is the intended hydraulic fluid.
