As a common valve type, butterfly valves are widely used in various industrial piping systems. The material and specifications of butterfly valves directly affect their performance, life and reliability in practical applications. This article will analyze the materials and specifications of Chinese butterfly valves in detail from a professional perspective to help you have a deeper understanding of butterfly valves.
The material of butterfly valve is mainly divided into the following types:
(1) Carbon steel: carbon steel butterfly valve is suitable for general industrial pipelines, with good tensile strength, toughness and wear resistance. Carbon steel butterfly valve can be subdivided into ordinary carbon steel butterfly valve and alloy carbon steel butterfly valve, respectively, suitable for different working conditions.
(2) Stainless steel: Stainless steel butterfly valve is mainly suitable for corrosive media and food hygiene. Stainless steel has good corrosion resistance and can effectively resist the erosion of acid, alkali, salt and other media.
(3) Alloy steel: alloy steel butterfly valve is suitable for high temperature, high pressure and other special conditions. Alloy steel has high tensile strength, toughness and wear resistance, and can maintain stable operation under high temperature and high pressure conditions.
(4) Cast iron: Cast iron butterfly valve is suitable for low pressure, low temperature civil construction and industrial fields. Cast iron has good seismic performance and sealing performance, while the price is relatively low, cost-effective.
2. Butterfly valve specifications
Butterfly valve specifications are mainly divided according to the following parameters:
(1) Size: The size of the butterfly valve includes nominal diameter, flange size, etc. The nominal diameter refers to the standard caliber specified in the design of the butterfly valve, and the flange size directly affects the connection between the butterfly valve and the pipeline system.
(2) Working pressure: The working pressure of the butterfly valve determines its pressure bearing capacity in practical applications. Butterfly valves are divided into low pressure, medium pressure and high pressure butterfly valves, customers should choose the appropriate working pressure level according to the actual working conditions.
(3) Operating temperature: The operating temperature of the butterfly valve determines its performance under different working conditions. According to the different operating temperatures, butterfly valves can be divided into normal temperature butterfly valves, high temperature butterfly valves and low temperature butterfly valves.
(4) Valve body form: butterfly valve body form includes straight-through, curved, three-way, etc. Butterfly valves with different body forms are suitable for different pipeline system layouts, and customers can choose the right body form according to actual needs.
The material and specifications of China’s butterfly valve cover many aspects, customers should be combined with the actual application scenario when choosing the butterfly valve, fully consider the performance of the butterfly valve, service life and reliability and other factors, choose the most suitable for their own butterfly valve products. In-depth knowledge of butterfly valve materials and specifications will help you better grasp the development trend of the butterfly valve market and provide strong support for engineering and industrial applications.
