Butterfly valve is often used to replace the traditional gate valve, globe valve ball valve because of its advantages such as wide temperature pressure range, good cut-off performance long service life. With the continuous development of modern technology materials, the application scope of butterfly valve has been far beyond the past, almost can replace most of the traditional valves.
Because the closing of butterfly valve gate valve is the same, it is completed by torque. The greater the closing torque of valve, the better the tightness of valve seat. Therefore, butterfly valve is called 90 ° rotary gate valve. In the overhaul repair of the factory, more more butterfly valves have replaced gate valves. Therefore, some manufacturers of butterfly valves have specially produced a kind of butterfly valve with the same length as the gate valve, this kind of butterfly valve is called gate valve.
Butterfly valve in the use of products, the most important is the sealing of the product, once the product sealing problems, there is no way to ensure the product. It is necessary to pay attention to whether the medium they are conveying is a high-temperature product a corrosive liquid?
The above content is to give you a detailed explanation of butterfly valve in use to pay attention to the knowledge of sealing, I believe you have further study understanding. If you want to know more, please continue to pay attention to our website.
