Pressure Relief Valve DBW 30 BG2-5X/315YU6EG12N9K4/12 - Bosch Rexroth R978917256
A 12 V control should unload the circuit just as a 24 V machine does. The DBW 30 BG2-5X brings a built-on directional spool valve for that, works between 2 and 315 bar and relieves up to 650 l/min through three ports in size 32.

Description
Electrical unloading of the pump does not depend on the voltage level but on the coil. The pilot-operated pressure relief valve DBW 30 BG2-5X/315YU6EG12N9K4/12 runs on 12 VDC, unloads through a built-on directional spool valve and covers 2 to 315 bar.
Benefits
- Unloading through a built-on directional spool valve at 12 VDC.
- Three ports and threaded connection in size 32.
- Setting range 2 to 315 bar, symbol B, maximum operating pressure 350 bar.
- Up to 650 l/min relief flow, pressure valve in poppet seat design.
- NBR seals, 6.3 kg, HL hydraulic fluid, internal hexagon with protective cap.
Application
Mobile power units and small machines on a 12 V supply cycle their pump like large ones do. The built-on directional spool valve switches the circuit pressureless during the pause and reduces oil heating. The threaded connection allows fitting into existing lines.
