Product Description

This electric hard-seal butterfly valve drives the butterfly plate to rotate through an electric device to achieve the functions of cutting off and regulating the medium in the pipeline. The hard-seal structure adopts metal-to-metal sealing, which makes it have excellent high temperature resistance, high pressure resistance, wear resistance and corrosion resistance. It can operate stably under complex working conditions such as particles, crystals, high temperature and high pressure; the flange connection method ensures that the valve and the pipeline are firmly combined to effectively prevent leakage.

Our electric hard-seal butterfly valve has become a key equipment for modern industrial pipeline fluid control with its high-precision control, reliable performance and automated operation.
