◼PRODUCT DESCRIPTION

After the high-performance butterfly valve is opened, the butterfly plate can quickly leave the valve seat, greatly eliminating the unnecessary excessive extrusion and scraping between the butterfly plate and the valve seat, reducing the opening resistance, reducing wear and tear, and increasing the life of the valve seat. It is mainly suitable for drainage in water plants, power plants, steel mills, chemical industry, water source projects, environmental facilities construction and other systems, especially suitable for use as a regulating and intercepting device on waterway pipelines.
