In the butterfly valve market in China, there are many different specifications and models of butterfly valve products to meet the needs of various engineering and industrial applications. This article will introduce the specifications and models of Chinese butterfly valves from a professional perspective to help you better understand and choose the butterfly valve products that suit your needs.
1. Type by connection mode
The butterfly valve can be divided into wire connection butterfly valve, flange connection butterfly valve, clamp connection butterfly valve, welding connection butterfly valve and so on. Different connection modes of butterfly valves are applicable to different engineering scenarios. Customers can select a proper connection mode based on actual application requirements.
2. Sort by material
The material of butterfly valve directly affects its performance and application field. Common butterfly valve materials are carbon steel, stainless steel, alloy steel, cast iron and so on. Carbon steel butterfly valve is suitable for general industrial pipelines, stainless steel butterfly valve is suitable for corrosive media and food hygiene fields, alloy steel butterfly valve is suitable for high temperature, high pressure and other special conditions, cast iron butterfly valve is suitable for low pressure, low temperature civil construction and industrial fields.
3. Sort by structure
Butterfly valve according to the structure can be divided into center butterfly valve, eccentric butterfly valve, three eccentric butterfly valve, etc. The center butterfly valve is simple in structure and easy to operate, and is suitable for general industrial pipelines; The eccentric butterfly valve has good sealing performance and is suitable for corrosive media and low noise occasions. The three-eccentric butterfly valve has better flow regulation performance and is suitable for occasions where the flow rate needs to be adjusted accurately.
4. Sort by job stress
According to the working pressure, butterfly valves can be divided into low pressure butterfly valves, medium pressure butterfly valves, high pressure butterfly valves, etc. Low pressure butterfly valve is suitable for low pressure pipe system, medium pressure butterfly valve is suitable for medium pressure pipe system, high pressure butterfly valve is suitable for high pressure pipe system. When selecting the butterfly valve, the customer should select the appropriate working pressure level according to the actual application scenario.
5. Classification by operating temperature
Butterfly valves can be divided into normal temperature butterfly valves, high temperature butterfly valves, low temperature butterfly valves and so on. The normal temperature butterfly valve is suitable for general industrial pipelines, the high temperature butterfly valve is suitable for high temperature conditions, such as thermal system, petrochemical industry, etc., and the low temperature butterfly valve is suitable for low temperature conditions, such as refrigeration system and liquefied gas transmission.
To sum up, there are many specifications and models of butterfly valves in China, and customers can choose from different aspects such as connection mode, material, structure, working pressure and working temperature to meet the needs of various engineering and industrial applications. In the purchase of butterfly valves, customers should be combined with the actual application scenario, 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.
