What is a fluorine-lined valve? How to extend the service life of it?
Fluorine-lined valves are made by using PTFE resin (or profile processed) to be molded (or inlaid) on the inner wall of the steel or iron valve pressure part or the outer surface of the valve inner part, and use its The unique performance of the anti-corrosive medium valve is made into various types of valves […]
Structure of Triple Eccentric Metal seated Butterfly Valve (Picture)
Butterfly valves can be divided into soft-sealed butterfly valves and metal seated butterfly valves according to the sealing form. This article mainly analyzes the structure of the triple eccentric metal seated butterfly valve. Metal hard seal butterfly valves are usually used in some high temperature and high pressure environments. They are mainly composed of valve […]
Application of double eccentric butterfly valve and triple eccentric butterfly valve
Butterfly valves can be divided into centerline butterfly valves, single eccentric butterfly valves, double eccentric butterfly valves and triple eccentric butterfly valves. These butterfly valves are widely used in our production and life. Because of some defects of the centerline butterfly valve itself, it is not suitable for the environment where the temperature and pressure […]
Application of Soft Seal Wafer Butterfly Valve in Sewage Treatment
The soft-seal wafer butterfly valve is now closely inseparable from various township sewage treatment plants. In the past agricultural villages, the sewage discharge facilities of farm households have not been transformed, resulting in the direct discharge of a large amount of domestic sewage, which seriously affected the lives of local villagers and threatened the ecological […]
Information about stainless steel wafer butterfly valve
Stainless steel wafer butterfly valves are metal butterfly valves. Metal valves generally have a longer life than elastic sealing valves, but it is difficult to achieve a complete seal. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature. The structure of stainless steel […]
Product Features of Electric Wafer Butterfly Valve
The electric wafer butterfly valve belongs to a variety of electric control valves. Its connection methods are mainly: flange type and wafer type. Its sealing forms mainly include: soft seal and metal hard seal. The electric wafer butterfly valve controls the switching operation of the butterfly valve through the power signal, and can be used […]
Types of Sealing Material of Electric Wafer Butterfly Valve
Electric wafer butterfly valves can be divided into soft-sealed butterfly valves and hard-sealed butterfly valves, which are distinguished according to the sealing materials of electric butterfly valves. The soft sealing butterfly valve’s sealing feature is that one side of the two sides is made of metal material, and the other side is made of elastic […]
Commonly used valve body materials of centerline wafer butterfly valve
The centerline butterfly valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc. Under the action of pressure, temperature or other forms of sensing signals, it can act according to predetermined requirements, or simply open or close […]
Resilient seated vs metal seated wafer butterfly valve
The soft-seal wafer butterfly valve contains two characteristics, one is that the sealing form is a soft seal, and the other is the connection method is a wafer. Wafer butterfly valves are divided into soft sealing butterfly valves and hard sealing butterfly valves. Soft seal means that one side of the butterfly valve sealing pair […]
Is a gasket needed for installation of the resilient seated wafer butterfly valve?
Before understanding the problem of adding gaskets to the soft-seal wafer butterfly valve, let’s take a look at the main working conditions of the soft-seal wafer butterfly valve. It can be applied to water supply and drainage, gas pipelines such as food, medicine, chemical industry, petroleum, electric power, textile papermaking, etc. It is used for […]
