On shutdown a pump has to be able to circulate unloaded, otherwise it works against a closed valve. The pump safety block DBAWR40BH2N1X/315S6SMG24N9K4B12E unloads electrically through a built-on seat valve and limits pressure up to 350 bar.

Applications
The block sits directly at the pump outlet of power units in presses, test rigs and special machinery. During start-up and idle periods the pump circulates unloaded through the switched relief path, which saves drive power and limits oil heating. The pressure setting is reached through an internal hexagon and secured against adjustment by a protective cap.
