Pressure Relief Valve DBW20B1-5X/210-6EG24N9K4E - Bosch Rexroth R901431864

In the medium pressure band around 210 bar the cut-off pressure is corrected more often than in high pressure circuits, because many different tools run there. The rotary knob on this version takes those corrections without a tool. The pilot-operated poppet valve in size 25 discharges up to 400 l/min and weighs 5.46 kg.

Benefits

• Rotary knob covering a setting range of 4 to 210 bar
• Pilot-operated poppet valve with a flat curve up to 400 l/min
• Subplate mounting to ISO 6264-08-13, size 25 body
• Spool symbol B, two switching positions and two ports
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.46 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

Power units in machining and fixture building are the target, where clamping pressure is matched to each component. A range up to 210 bar is enough for the standard cylinders used in such fixtures. The solenoid switches the circuit without moving the knob position.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B1-5X/210-6EG24N9K4E under material number R901431864. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. A pressure gauge in the circuit makes setting the knob considerably easier.
