Pressure Relief Valve DBW20B2-5X/200S6EG24N9K4QMBG24R12 - Bosch Rexroth R901573216

Between working strokes the pump should circulate without pressure, during the stroke the pressure has to be limited cleanly. This version of the pilot-operated DBW 20 in size 25 does both, across 4 to 200 bar at flow rates up to 500 l/min.

Benefits

• Setting range of 4 to 200 bar at a maximum operating pressure of 350 bar
• Circuit unloading through solenoid actuation at 24 VDC across two switching positions
• 3-pole valve plug (2 + PE) to EN 175301-803, widely stocked and easy to replace
• Subplate interface to ISO 6264-08-13 for flow rates up to 500 l/min
• Seat-type pilot stage with internal hexagon and protective cap for pressure adjustment

Application

It suits power units with long idle periods, such as clamping systems, presses and test rigs. Unloaded circulation keeps oil heating down. The valve weighs 6.7 kg and runs NBR seals in HL grade mineral oil.
