The German messko pressure relief valve MPreC series LMPRD is suitable for large and medium-sized distribution transformers, power transformers, and tap changers. It is mainly used to protect the pressure release of transformers and tap changers. When the pressure exceeds the limit value, the valve cover will rise and the seal will open, and the entire process will be completed within a few milliseconds. After the pressure drops below the limit value, the valve closes and returns to the sealed state. The release range of the pressure relief valve is 4-30psi (0.28-2.07 bar).
