Pressure Relief Valve DBW20A2-5X/310-6EG24N9K4E - Bosch Rexroth R901262605

Some machines are documented at 310 bar because a single component in the circuit sets that limit. A setting range of 4 to 310 bar meets the requirement without raising the cut-off point to the next catalogue step. The pilot-operated poppet valve with spool symbol A takes 400 l/min and is adjusted on the internal hexagon under the protective cap.

Benefits

• Setting range 4 to 310 bar for tightly documented machine limits
• Spool symbol A, two switching positions, two ports
• Flow up to 400 l/min across the ISO 6264-08-13 subplate interface
• Pilot-operated poppet valve in size 25, maximum operating pressure 350 bar
• 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 usual case is an accumulator, a hose or a cylinder head that dictates the pressure limit of the machine, with the cut-off pressure having to stay below it. A setting range up to 310 bar allows that without compromise. Solenoid actuation switches the circuit without changing the value that was set.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20A2-5X/310-6EG24N9K4E under material number R901262605. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Record which component dictates the 310 bar limit so it is not lost during later modifications.
