Introduction to manual butterfly valve

The manual butterfly valve is a flanged butterfly valve and a pipe expander. The manual butterfly valve can not only throttle, but also eliminate the internal force generated by temperature difference. The manual butterfly valve can expand and contract. The manual butterfly valve can be used for regulating and intercepting the flow in electric power, metallurgy, petroleum, chemical industry, coal gas, urban heating, hydropower and papermaking, textile, medicine, food, water supply and drainage, energy, all non-corrosive gas, liquid, semi-fluid and solid powder pipelines and vessels. The manual butterfly valve can be installed at any position without being affected by the medium and flow direction.

The manual butterfly valve is used for adjusting the distance between two flanges during valve installation.
