2-piece Threaded Ball Valve, More Corrosion-resistant Than Stainless Steel Valves

1. Stainless steel's corrosion resistance isn't ideal. Is there an alternative? -- 2 Piece Threaded Ball Valve

With the continuous advancement of chemical technology, people's lives are no longer inseparable from chemical products. However, most chemical raw materials are highly corrosive, either strong acids or strong bases. Ordinary stainless steel cannot withstand the strong corrosion of these raw materials, which has become a problem for valve wear. Is there something that can replace stainless steel and become a new corrosion-resistant valve?

2. Why are fluorine-lined valves more corrosion-resistant than stainless steel valves?

Fluorine-lined valves in valve production use polytetrafluoroethylene. Polytetrafluoroethylene resin (or processed profiles) is molded (or inlaid) onto the inner wall of steel or iron valve pressure-bearing components (the same method is used for lining various pressure vessels and piping accessories) or the outer surface of valve internals. This unique resistance to highly corrosive media is utilized to create various valves and pressure vessels. Suitable for use with organic solvents or reagents, dilute or concentrated inorganic acids, alkalis, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, etc. Operating temperature: -85°C to 150°C. Features: Mechanical, electrical, and chemical stability are essentially the same as F4, with the single most prominent advantage being high dynamic impact resistance, excellent weather resistance, and radiation resistance.

3. What types of fluorine-lined valves are there?

Using a fully one-step extrusion process, we can meet the requirements of pipelines with PTFE linings. We can produce a range of common fluorine-lined valves, including ball valves, globe valves, butterfly valves, and check valves. Specialty valves can also be customized to meet specific needs.

Due to the location and usage of pipelines, a single pipeline often has many different valves.

1. Fluorine-lined butterfly valve: For quick closing of small-diameter pipelines, a 90-degree quick-opening fluorine-lined butterfly valve is generally used. Its small size allows for unrestricted installation locations, and it is easy to open and close, making it the most commonly used valve type.

2. Fluorine-lined gate valve: For large flow requirements and large diameters, a fluorine-lined gate valve is generally used. The fully lined gate disc increases the flow rate of the medium and improves production efficiency.

3. Fluorine-lined ball valves: Fluorine-lined ball valves are often used for high flow rates and fast opening and closing. Their full-bore design and fast opening and closing make them the most commonly used type of fluorine-lined valve.

4. Fluorine-lined stop valves: Fluorine-lined stop valves are commonly used for regulating flow and sealing gases. Their low-inlet and high-outlet design can buffer pipeline flow rates and adjust flow rates.

5. Fluorine-lined check valves: Fluorine-lined check valves are commonly used for preventing backflow and reverse flow in pipelines. They provide an automatic mechanical seal to prevent backflow and ensure the safety and maintenance of pipeline equipment.
