Pressure Relief Valve DBW20B2-5X/180Y6EG24N9K4E - Bosch Rexroth R901086650

Large cylinders reach their force through area rather than pressure, which is why 180 bar is often enough while the flow stays high. This version is released for 450 l/min and covers a setting range of 4 to 180 bar. The pilot-operated poppet valve mounts on a subplate to ISO 6264-08-13 and weighs 6.9 kg.

Benefits

• 450 l/min flow rating with a setting range of 4 to 180 bar
• Pilot-operated poppet valve in size 25 with spool symbol B
• Maximum operating pressure 350 bar, well clear of the setting stage
• Internal hexagon with protective cap, subplate mounting to ISO 6264-08-13
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 6.9 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

The valve serves power units for platen presses, lifting tables and large clamping cylinders that swallow a lot of volume at moderate pressure. The flow headroom stops pressure from rising above the set point when the cylinder runs onto its end stop. The solenoid switches the circuit from the machine control.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/180Y6EG24N9K4E under material number R901086650. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Check that return line and filter take 450 l/min without noticeable back pressure.
