Pressure Relief Valve DBW 30 BG2-5X/315YU6EG12N9K4/12 - Bosch Rexroth R978917256

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.
