Product Overview: 

LXHQ-CLBVF lined flanged butterfly valve is a midline flanged butterfly valve with integral lining of anticorrosive materials (such as PTFE, PFA, FEP, PO, etc.) on the inner wall of the valve body and the surface of the butterfly plate. It has reasonable structural design, excellent corrosion resistance and sealing performance, and is especially suitable for strong corrosive media, clean working conditions and high-frequency opening and closing occasions. The opening and closing angle of the butterfly plate is 0 ° -90 °, which is flexible to operate. Standard flange interfaces are adopted on both sides of the valve body, which is convenient for installation and maintenance. It is widely used in chemical, pharmaceutical, food, environmental protection and water treatment industries.
