Pressure Relief Valve DBW20A2-5X/220-6EG24N9K4E - Bosch Rexroth R901185760

A circuit whose cylinders are calculated for 220 bar needs a valve whose setting range ends right there. This version covers 4 to 220 bar and carries spool symbol A. The pilot-operated poppet valve discharges up to 400 l/min across the ISO 6264-08-13 subplate interface and weighs 5.36 kg.

Benefits

• Setting range 4 to 220 bar, matching a design pressure of 220 bar
• Spool symbol A with two switching positions
• Pilot-operated poppet valve in size 25 rated for up to 400 l/min
• Subplate mounting to ISO 6264-08-13, internal hexagon with protective cap
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.36 kg mass, NBR seals for HL hydraulic fluid

Application

The valve serves power units feeding clamping cylinders and feed drives at 220 bar. Because the setting range ends at the design pressure, the cut-off point cannot accidentally be turned beyond it. Solenoid actuation switches the circuit from the control system.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20A2-5X/220-6EG24N9K4E under material number R901185760. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. If system pressure is raised later, a valve with a wider setting range becomes necessary.
