Pressure Relief Valve DBW20A2-5X/350S6EG24N9K4R12/12 - Bosch Rexroth R901228742

Whether a circuit stays pressurised or unloaded without power depends on the symbol of a built-on directional valve. The pilot-operated DBW20A2-5X/350S6EG24N9K4R12/12 works to spool symbol A, can be set from 4 to 350 bar and accepts up to 500 l/min.

Benefits

• Spool symbol A in two switching positions with 24 VDC solenoid actuation.
• Pressure adjustment range 4 to 350 bar at a maximum of 350 bar operating pressure.
• Up to 500 l/min in size 25 to ISO 6264-08-13.
• Poppet design with an internal hexagon and protective cap on its adjustment.
• 5.94 kg, NBR seals for HL hydraulic fluid.

Technical data

Application

It is installed in a pressure port of power units whose control system switches a circuit deliberately. Choosing between symbol A and symbol B follows from the behaviour wanted on loss of power and should be checked before replacement.
