Pressure Relief Valve DBW10A2-5X/350S6EG24N9K4R12/12 - Bosch Rexroth R978018592

The adjustment range of this valve runs from 4 to 350 bar and so covers the whole permitted operating pressure. The pilot stage works as a seat valve and is set through an internal hexagon with a protective cap. In size 10 up to 250 l/min are relieved.

Benefits

• Adjustment range of 4 to 350 bar, matching the maximum operating pressure
• 250 l/min relief capacity to the ISO 6264-06-09 interface
• Spool symbol A with two switching positions and two ports
• Pilot-operated seat valve for low leakage in holding duty
• Electrical unloading through the solenoid at 24 VDC
• Internal hexagon with protective cap, NBR seals, weight 4.3 kg

Technical data

Applications

The valve protects circuits that work close to 350 bar continuously, such as clamping hydraulics and compact press power units. Since the adjustment range extends to the permitted operating pressure, the rating of the surrounding components has to be kept in mind when setting it. The solenoid unloads the circuit on command.
