Butterfly valve is a kind of valve that uses disc type opening and closing parts to turn back and forth about 90 degree to open, close and adjust the fluid passage. Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also has good flow regulation function and closing and sealing characteristics at the same time. One of the fastest growing valve varieties. Especially in industrialized countries such as the United States, Japan, Germany, France, and Italy, butterfly valves are widely used, and the variety and quantity of them are still expanding, and they are developing to high temperature, high pressure, large diameter, high sealing, long life, Excellent adjustment characteristics and multi-functional development of a valve, its reliability and other performance indicators have reached a high level, and have partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valves will become the dominant valve form in the foreseeable short period of time, especially in the field of medium and low pressure applications of large and medium-sized ports.
· Fully rubber-lined valve body design
