Pressure Relief Valve DBW20B2-5X/190-6EG24N9K4E - Bosch Rexroth R901402226

Accumulator circuits and cylinders with limited piston force often call for a cut-off pressure just under 200 bar. A setting range of 4 to 190 bar delivers that directly, and the cap over the internal hexagon holds the value after commissioning. The ISO 6264-08-13 subplate interface takes up to 400 l/min.

Benefits

• Setting range 4 to 190 bar for circuits just below the 200 bar mark
• Flow up to 400 l/min, size 25 body, maximum operating pressure 350 bar
• Internal hexagon with protective cap holds the setting
• Pilot-operated poppet valve with spool symbol B and 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

Typical cases are accumulator charging circuits whose charge pressure must stay below the test pressure of the accumulator, and cylinders with a limited rod load. The pilot-operated design keeps pressure stable across the whole flow range. The solenoid switches the circuit without touching the stage that was set.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/190-6EG24N9K4E under material number R901402226. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Keep the cut-off pressure clearly below the permissible operating pressure of the connected components.
