Two-way hard-to-hard butterfly valves are widely used in industrial pipelines such as low pressure, medium pressure, high pressure, steel metallurgy, petrochemical industry, electric power, etc., to block or regulate the flow of media. This article introduces the structural characteristics and precautions of the two-way hard-touch hard butterfly valve.

The structural characteristics of the two-way hard-touch hard butterfly valve eliminates the shortcomings of other types of butterfly valves that cannot be sealed due to over-opening, and can be used normally at high temperatures, and overcomes the simple shortcomings of other types of valves. .If used at high temperature, leakage will occur due to thermal expansion. The butterfly valve tiller requires different sealing surface materials to ensure that the sealing surface is wear-resistant, corrosion-resistant and has a long service life.
