Lug Butterfly Valve
The valve body connection of the lug butterfly valve adopts a lug-style design, characterized by a compact structure and easy installation. The lug butterfly valve is a type of butterfly valve that uses high-polymer materials as lining on the flow components of the valve body and the valve disc. The lining material completely isolates the medium from the valve body, providing excellent corrosion resistance.
Due to the excellent corrosion resistance, the lug butterfly valve can be applied to control various fluids with different concentrations of acids, alkalis, organic solvents, etc. This flow control valve is mainly used in anti-corrosive transport systems in the chemical industry, petroleum transmission systems, wastewater treatment systems in the paper mills, high-temperature and high-pressure transport systems in the hydropower industry, as well as flow interception and flow rate adjustment in semi-fluid pipeline systems. It is an ideal industrial valve.
