Pressure Relief Valve DBW20B2-5X/120-6EG24N9K4E - Bosch Rexroth R901084788

Alongside the main drive, many machines run auxiliary circuits for tilting, clamping and repositioning that need little more than 100 bar. A setting range of 4 to 120 bar covers them without pushing the cut-off point into the bottom corner of a wide spring curve. The pilot-operated poppet valve takes up to 400 l/min.

Benefits

• Setting range 4 to 120 bar for auxiliary and peripheral circuits
• Flow up to 400 l/min in size 25
• Pilot-operated poppet valve with spool symbol B and two ports
• 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
• 5.38 kg mass, NBR seals for HL hydraulic fluid

Application

The stage is used on clamping and tilting circuits of machine tools, on feed units and on handling modules. Because the setting range is kept narrow, the cut-off pressure can be hit more precisely than with a widely spanned spring. The solenoid switches the circuit independently of the setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/120-6EG24N9K4E under material number R901084788. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. If demand in the auxiliary circuit later exceeds 120 bar, choose a version with a wider setting range.
