Product Description
Product Details of Manual Fluorine - Lined Butterfly Valve
Structure and Principle
- Structure: It mainly consists of valve body, butterfly disc, valve stem, handwheel, and fluorine - lined layer. The valve body is cylindrical, the butterfly disc is disc - shaped. The valve stem connects the butterfly disc and the handwheel, and the handwheel is for manual operation. The fluorine - lined layer covers the surfaces of the valve body and butterfly disc that contact the medium.
- Principle: By rotating the handwheel, it drives the valve stem to rotate, and the valve stem drives the butterfly disc to make a 90° rotational movement inside the valve body, realizing the opening, closing, or flow regulation of the valve. When the butterfly disc is fully open, the medium can pass through smoothly; when it is fully closed, the medium flow is cut off.
Materials
- Valve Body: Usually made of cast iron, cast steel, or stainless steel. The blue part in the picture may be cast iron with a surface treatment.
- Butterfly Disc: Mostly made of metal, such as stainless steel, with a fluoroplastic (e.g., polytetrafluoroethylene, PTFE) lining on the surface.
- Valve Stem: Generally made of corrosion - resistant and high - strength materials like stainless steel to ensure it is not easily damaged or corroded during long - term use.
- Lining: Fluoroplastics, which have excellent corrosion resistance, high and low - temperature resistance, low friction coefficient, and good non - stickiness. They can effectively resist the erosion of various strongly corrosive media.
Features
- Strong Corrosion Resistance: The fluorine - lined layer can resist various strong acids, alkalis, and oxidants, such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide, etc. It is suitable for applications in industries like chemical, pharmaceutical, food, and electroplating where corrosive media are transported.
- Good Sealing Performance: There is a good seal between the butterfly disc and the valve body, which can effectively prevent medium leakage.
- Easy to Operate: Operated by a handwheel, it rotates flexibly with a small opening and closing torque, making it convenient for manual operation.
- Long Service Life: The combination of fluoroplastic lining and high - quality metal parts reduces the erosion and wear of the medium on the valve, thus extending its service life.
Technical Parameters
- Nominal Diameter: Common specifications range from DN40 - DN600, etc.
- Nominal Pressure: Generally, there are PN1.0MPa, PN1.6MPa, etc.
- Applicable Temperature: Usually around - 40ºC - 150ºC, and the specific value varies depending on the type of fluoroplastic and working conditions.
- Applicable Media: Various corrosive liquids, gases, and other media, such as acid - base solutions, organic solvents, etc.
Application Fields
- Chemical Industry: Used for the transportation of chemical raw materials and the control of media during chemical reactions.
- Pharmaceutical Industry: Controls the transportation of various chemical reagents and liquid medicines during pharmaceutical production.
- Food Industry: Used for controlling media during the production of food additives, fruit juices, beverages, etc., meeting food hygiene requirements.
- Environmental Protection Industry: Controls the flow of corrosive media in sewage treatment, waste gas treatment, and other processes.
