Pressure Relief Valve DBW 30 BG2-5X/315U6EG125N9K4/12 - Bosch Rexroth R978915818

On pump start and during idle periods the circuit should circulate unloaded, yet stay properly limited in operation. The DBW 30 BG2-5X/315U6EG125N9K4/12 covers both in one body, with poppet seat pressure limitation for up to 650 l/min and electrical unloading through the built-on directional valve.

Benefits

• 650 l/min across 2 ports, connection diagram ISO 6264-10-17.
• 2 to 315 bar setting range at an internal hexagon with protective cap.
• Electrical unloading at 12 VDC through a 3-pole (2 + PE) connector to EN 175301-803.
• Poppet seat design in the pressure stage, built as a threaded connection rather than for subplate mounting.
• 2.97 kg at a maximum operating pressure of 350 bar in size 32.

Applications

Common in pump stations and press circuits of size 32 where circulation is unloaded between cycles. The threaded connection allows installation straight into the line without a separate subplate. NBR seals and HL fluid suit mineral oil.
