Messko pressure relief valve LMPRD

Messko pressure relief valve LMPRD

working principle:

Suitable for large and medium-sized distribution transformers, power transformers, and tap changers. Used for pressure relief to protect 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.
