Soft seal gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be adjusted and throttling.

1、Simple structure, good general interchangeability, low price. 2、Stem seal is not easy to deform so as to avoid the stem leakage phenomenon, the overall support performance is good, stable and firm. 3、The amount of seat rubber is small, the potential impact of expansion is small, easy to control the torque in the appropriate range.

Three eccentric metal sealed butterfly valve is a new generation of butterfly valve products developed by introducing German technology. Product performance has been better than the leading level at home and abroad, widely used in metallurgy, petroleum, chemical industry, electric power, municipal construction and other industrial pipelines for cutting off or regulating the flow of media.

Butterfly valve is a kind of valve that uses disc type opening and closing parts to turn back and forth about 90° to open, close or regulate the flow of medium. It not only has the advantages of simple structure, small volume, light weight, material consumption, small installation size, small driving torque, easy to operate, rapid, and can also have a good flow regulation and closing 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.

The centreline double flange butterfly valve is designed according to the requirements of large pipeline network and belongs to mesh valve.

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.
