The Difference Between A Lug and Wafer Butterfly Valve

2019-02-12 16:59:28

Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.

Wafer type butterfly valve installation instructions and steps

2019-01-03 16:27:13

The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.

RKSfluid Valve Analysis of the main application areas of the valve!

2021-07-12 09:47:21

Analysis of the main application areas of the valve!
With the various needs of modern life, spare parts for the production of these important products are also emerging in endlessly. The main application areas of the 10 categories of RKSfluid Valve are listed below.
1) Oil refining equipment. Most of the valves used in oil refining equipment are pipeline valves, mainly gate valves, stop valves, check valves, safety valves, ball valves, butterfly valves, and traps. Among them, the demand for gate valves accounts for about 80% of the total number of valves. (Valves account for 3% to 5% of the total investment of the device);
2) Chemical fiber device. Chemical fiber products mainly include polyester, acrylic and vinylon. Ball valves and jacketed valves (jacketed ball valves, jacketed gate valves, jacketed stop valves) of the valves they need;
3) Acrylonitrile device. The device generally requires standard valves, mainly gate valves, globe valves, check valves, ball valves, traps, needle globe valves, and plug valves. Among them, gate valves account for about 75% of the total valve;
4) Synthetic ammonia plant. Because the ammonia source and purification method are different, the process flow is different, and the technical function of the required valve is also different. At present, domestic ammonia plants mainly need gate valves, stop valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high temperature and low temperature valves;
2. Valves used in hydropower stations, and the construction of power stations in my country is developing towards large-scale, so large-diameter and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency blocking valves, flow control valves, and spherical seal instruments are needed. Shut-off valve, (according to the national "Tenth Five-Year Plan", in addition to Inner Mongolia and Guizhou provinces can build units with more than 200,000 kilowatts, other provinces and cities can only build units with more than 300,000 kilowatts);
3. Metallurgical application valves and alumina behavior in the metallurgical industry mainly require wear-resistant slurry valves (in-flow stop valves) and regulating traps. The steelmaking industry mainly needs metal-sealed ball valves, butterfly valves and oxidation ball valves, stop flash and four-way reversing valves;
4. Valves for marine applications. With the development of offshore oilfield exploitation, the amount of valves required for marine applications has gradually increased. Offshore platforms need to use shut-off ball valves, check valves, and multi-way valves;
5. Valves for food and medicine applications. The industry mainly needs stainless steel ball valves, all-plastic ball valves and butterfly valves. Among the above 10 types of valve products, the demand for general valves is more, such as instrument valves, needle valves, needle globe valves, gate valves, globe valves, check valves, ball valves, and butterfly valves.
6. Low-pressure valves are generally used in rural and urban construction applications, and urban construction systems are currently developing in the direction of environmental protection and energy saving. Environmentally friendly rubber plate valves, balance valves, centerline butterfly valves, and metal seal butterfly valves are gradually replacing low-pressure iron gate valves. Most of the valves used in domestic urban construction are balance valves, soft-sealed gate valves, butterfly valves, etc.;
7. In rural and urban heating valves and urban heat generation systems, a large number of metal-sealed butterfly valves, horizontal balancing valves, and direct-buried ball valves are required. These valves solve the problem of vertical and horizontal hydraulic imbalance of pipelines, and achieve energy saving and replacement. The purpose of heat balance.
8. Valves for environmental protection applications and domestic environmental protection systems, the water supply system mainly requires centerline butterfly valves, soft-sealed gate valves, ball valves, and exhaust valves (used to remove air in the pipeline). The sewage treatment system mainly needs soft-sealed gate valves and butterfly valves;
9. Gas valves and city gas account for 22% of the entire natural market. Valves are used in large quantities and have many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve;
10. Pipeline application valves and long-distance pipelines are mainly crude oil, finished products and natural pipelines. The most commonly used valves for this type of pipeline are forged steel three-piece full bore ball valves, anti-sulfur flat gate valves, safety valves, and check valves.
