Types of two-way pressure hard sealing butterfly valve

Everyone knows that the hard-sealed butterfly valve is a butterfly valve commonly used in industrial production. It is often installed in low-pressure pipelines to cut off and throttle the medium. It is mainly used in the environmental protection system of city gas, city natural gas, city hot and cold air, city steam pipeline and electric power engineering, and chemical smelting engineering. In order to meet the needs of industrial production, butterfly valve manufacturers have developed and designed a new type of two-way pressure hard-sealed butterfly valve. There are currently three types of two-way hard-sealed butterfly valves, one is a butt-welded two-way hard-sealed butterfly valve, the other is a wafer-type two-way hard-sealed butterfly valve, and the other is a flanged two-way hard-sealed butterfly valve. The functions of these three two-way pressure hard sealing butterfly valves are not much different. They are all designed with three-dimensional eccentric structure, but they are different in connection mode and structural design.
