Special Material Ball Valve

Production:
Special material ball valve is a new type of ball valve product, which can be applied to a variety of different working conditions due to its particularity in materials. According to different materials, special material ball valves can be divided into high temperature ball valves, corrosion-resistant ball valves, wear-resistant ball valves and low temperature ball valves.

1. High temperature ball valve

High temperature ball valve refers to ball valve products with operating temperature higher than 200 °C. This kind of ball valve mainly adopts metal sealing structure, which has complex structure and difficult manufacturing. The advantages of high temperature ball valve are reliable sealing, good impermeability, suitable for high temperature, high pressure, strong corrosion industrial occasions. Commonly used high-temperature materials are chromium-molybdenum steel, chromium steel, nickel alloy, etc.

2. Corrosion-resistant ball valve

Corrosion-resistant ball valve is suitable for flow control of various strong corrosive media, such as acid, alkali, salt, etc., commonly used materials are PTFE, fluoroplastic, FRP, etc. This ball valve is corrosion-resistant, durable, and material-stable. Due to the special nature of this material, the production cost of corrosion-resistant ball valves is high, and the manufacturing process is required to be very strict.

3. Wear-resistant ball valve

Wear-resistant ball valves are ball valves that require anti-wear properties when transporting fluids containing particles. This material usually uses silicon carbide, cemented carbide, etc., which has wear resistance and high temperature resistance. Wear-resistant ball valves are suitable for circulating water, wastewater treatment, pulping, carbon mine, smelting and other fields.

4. Low temperature ball valve

Low temperature ball valve refers to ball valve products with operating temperature below -40 °C. Common low-temperature materials are stainless steel, low-temperature carbon steel, copper alloy, etc. The low temperature ball valve mainly adopts socket structure, which has good sealing and flexible operation. Cryogenic ball valves are commonly used in liquid oxygen, liquid ammonia, liquid natural gas (LNG), liquid methane and other occasions.

Design characteristics:

The design characteristics of special material ball valves are to select materials and design according to the requirements of working conditions to meet the process needs of different occasions. Any kind of special material ball valve needs to consider sealing, durability, reliability, safety and other issues. At the same time, due to the particularity of the material itself, the manufacture of special material ball valves is more difficult, and the production process is more stringent.

The application conditions of special material ball valves are very extensive, including chemical, petroleum, metallurgy, electric power, pharmaceutical, health, municipal and other fields. In these fields, the corrosion resistance, high temperature resistance, wear resistance and other characteristics of special material ball valves have been widely used. With the continuous progress of industrial development, the application range of special material ball valves will become more and more extensive, and continuous innovation and development will promote the application and promotion of higher level products of special material ball valves.
