The fluorine lined butterfly valve is a valve product that derives its name from its structure and materials. Specifically, the interior of a fluorine lined butterfly valve is lined with a material such as fluorine plastic (PTFE or FEP), known as "fluorine lining".
The internal lining of a fluorine lined butterfly valve is usually made of fluorine plastic (PTFE or FEP) and other materials, which have excellent corrosion resistance and high temperature resistance and can withstand a variety of strong acids, strong alkalis, strong oxidants, and other highly corrosive media, up to 400°C and 10MPa high pressure. At the same time, fluorine plastic also has good non-stick and wear resistance, which makes the sealing surface of fluorine lined butterfly valve not easy to wear and has a long service life.
The structure of the fluorine lined butterfly valve is similar to butterfly wings. Due to its small size, light weight, easy installation, maintenance, and flexible operation, it is widely used for media control and flow regulation in various harsh environments. The advantages of fluorine lined butterfly valve are good corrosion resistance, good sealing performance, simple structure, wide range of use, economical and practical, etc. It is widely used in the chemical, pharmaceutical, food, and metallurgical industries.
Different materials:
Fluorine lined butterfly valves are lined with fluorine material inside and steel or cast iron outside, while ordinary butterfly valves are made of a single material, such as cast iron, cast steel, stainless steel, etc.
Different corrosion resistance:
Fluorine lined butterfly valves have excellent corrosion resistance and can adapt to various corrosive media; while ordinary butterfly valves do not have such high corrosion resistance.
Different sealing performance:
The internal fluorine lining material of fluorine lined butterfly valve can effectively protect the sealing surface of the valve and prevent leakage, while ordinary butterfly valves do not have such internal fluorine lining material, and the sealing performance is relatively poor.
Different prices:
As fluorine lined butterfly valves use high quality materials such as internal fluorine lining materials, the prices are relatively high, while ordinary butterfly valves are relatively low.
In short, there are differences between fluorine lined butterfly valves and ordinary butterfly valves in terms of materials, corrosion resistance, sealing performance and price, etc. Users can choose the right valve products according to their actual needs.
Excellent corrosion resistance:
Fluorine lined butterfly valve internal fluorine lining material can effectively resist the erosion of various corrosive media with excellent corrosion resistance.
Good sealing performance:
The internal fluorine lining material of the fluorine lined butterfly valve can effectively protect the sealing surface of the valve to prevent leakage and has good sealing performance.
Simple structure and light weight:
The structure of the fluorine lined butterfly valve is simple, small in size and light in weight, and easy to install and maintain.
Convenient operation:
The fluorine lined butterfly valve has a small torque when opening and closing, is easy to operate, and is suitable for manual, electric, and pneumatic operation.
Wide range of use:
Fluorine lined butterfly valve is suitable for various corrosive media, high temperature and high pressure working conditions, and special industries, with a wide range of applications.
Economical and practical:
Fluorine lined butterfly valves are made of high quality materials such as internal fluorine lining materials, but due to the simple structure, the price is relatively low and economical and practical.
Highly corrosive media:
The internal fluorine lining material of fluorine lined butterfly valve can withstand various strong acids, strong alkalis, strong oxidants, and other highly corrosive media.
High temperature and high pressure working conditions:
Fluorine lined butterfly valves are suitable for high temperature and high pressure working conditions. They can withstand high temperatures of 400℃ and high pressure of 10MPa at the highest.
Food and the pharmaceutical industry:
Fluorine lined butterfly valve meets the sanitary standards of the food and pharmaceutical industry and can be used in production.
Chemical industry:
Fluorine lined butterfly valves can be used to produce, store, and transport various chemicals.
Oil and gas industry:
Fluorine lined butterfly valves can be used to produce, store, and transmit oil and gas.
In short, fluorine lined butterfly valves are suitable for use in various corrosive media, high-temperature and high pressure working conditions, and special industries. When choosing fluorine lined butterfly valves, users should select the appropriate valve type and material according to the actual working conditions and media characteristics.
