A pump circuit running up to 650 l/min needs pressure limitation that can also be unloaded electrically. The DBW 30 BG2-5X limits within a 2 to 315 bar setting range and switches to unloaded circulation through a built-on directional valve on 12 VDC. 2.97 kg, threaded connection.

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.
