Product overview
Butterfly valve is a kind of valve that uses disc type opening and closing parts to reciprocate about 90° to open, close or regulate the flow of medium. It not only has the advantages of simple structure, small size, light weight, material consumption, small installation size, small driving torque, easy to operate, rapid, and can also have a good flow control function and close the sealing characteristics, is one of the fastest-growing valve varieties in recent years. Butterfly valve is easy to combine with various driving devices, has good durability and reliability. Its use in a wide range of fields, the use of varieties and the number of rising trend, and to high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, as well as a multi-functional development of the valve, its reliability and other performance indicators have reached a high level.

1、The valve body is LT type, which can be used at the end of pipeline.
2、The sealing ring of ‘○’ type is directly set in the shaft hole of the valve body, which has better sealing and eliminates the occurrence of internal leakage.
3、Narrow band sealing ring and spherical butterfly plate organic combination, so that the butterfly plate before closing torque will not increase.
4、The convex circle on the top of the valve seat can avoid the possibility of the valve being installed incorrectly and the torque of the valve being sharply increased by the serious deformation of the valve seat. -
