Pressure Relief Valve DBW20B2-5X/100-6EG24N9K4E - Bosch Rexroth R901128689

Test specifications and low pressure circuits frequently name exactly 100 bar, whether for leak testing or for cylinders with a large piston area. A setting range of 4 to 100 bar reproduces that figure with fine resolution. The pilot-operated poppet valve discharges up to 400 l/min and weighs 4.95 kg.

Benefits

• Setting range 4 to 100 bar with fine resolution around the 100 bar figure
• 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
• 4.95 kg mass, NBR seals for HL hydraulic fluid

Application

The stage is used on test benches for leak and pressure testing, in circuits with large area cylinders and in machines whose components are limited to 100 bar. The 350 bar rating of the body protects the valve against damage from pressure peaks. The solenoid switches the circuit from the control system.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/100-6EG24N9K4E under material number R901128689. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. For repeatable tests, fit a gauge with a suitable measuring range to the circuit.
