Pressure Relief Valve DBW30A1-5X/350S6EG24N9DL/R12 - Bosch Rexroth R900749211

Spool symbol A across two switching positions decides how the circuit is led while the DBW30A1-5X/350S6EG24N9DL/R12 unloads. The pilot-operated seat valve in size 32 adjusts from 4 to 350 bar and passes up to 650 l/min at 350 bar maximum operating pressure. Subplate mounting follows pattern ISO 6264-10-17 at a weight of 7.1 kg.

Technical data

Applications

The valve serves as main pressure limitation on pump units whose circuit is relieved between cycles. Its rotary knob allows the target pressure to be trimmed during operation anywhere inside the 4 to 350 bar band. At 650 l/min the return line to tank has to be sized generously so back pressure stays low.
