10 major categories of valves main areas of application

1. Control Valves: Process control systems in various industries 2. Ball Valves: Oil and gas pipelines, water treatment plants 3. Gate Valves: Water supply systems, wastewater treatment plants 4. Butterfly Valves: HVAC systems, chemical processing plants 5. Globe Valves: Steam systems, power plants 6. Check Valves: Pumping systems, marine applications 7. Plug Valves: Oil refineries, petrochemical plants 8. Diaphragm Valves: Pharmaceutical industry, food processing 9. Pressure Relief Valves: Pressure vessels, safety systems 10. Safety Valves: Boilers, industrial equipment

With the various needs of modern life, then the production of spare parts for these important products is also endless. Below we list the main application areas of these 10 categories of valves.

1. 石头通过带阀门的装置传送。

Oil refining unit requires most of the valves are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, of which, the gate valve needs to account for the total number of valves about 80%, (valves accounted for the total investment in the device 3% to 5%).

Chemical fiber device, chemical fiber products are mainly polyester, acrylic, polyvinyl chloride three categories. Its need for valves of ball valves, jacketed valves (jacketed ball valves, jacketed gate valves, jacketed globe valves);

The device generally needs to use various types of valves, including 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 number of valves.

Ammonia plant: gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high temperature and low temperature valves.

China's power plant construction is developing towards large-scale, requiring large-diameter and high-pressure safety valves, pressure-reducing valves, globe valves, gate valves, butterfly valves, emergency blocking valves, and flow control valves, as well as spherical seal instrumentation globe valves. According to the national "Tenth Five-Year Plan," provinces other than Inner Mongolia and Guizhou can build units of 200,000 kilowatts or more, while other provinces and cities can only build units exceeding 300,000 kilowatts.

Metallurgical applications valves, metallurgical industry, alumina behavior is mainly required to wear-resistant slurry valve (in the flow of stop valve), regulating traps. Steelmaking industry mainly requires metal-sealed ball valves, butterfly valves and oxidation ball valves, cut-off flash and four-way directional valves;

Marine platforms require shut-off ball valves, check valves, multi-way valves.

5,食品和医药应用阀门，该行业主要需要不锈钢球阀、无毒全塑料球阀和蝶阀。上述10大类阀门产品中，对通用阀门的需求较多，如仪表阀门、针阀、针型截止阀、闸阀、截止阀、止回阀、球阀、蝶阀等。

The countryside, urban construction applications valves, urban construction system with the general use of low-pressure valves, is currently being developed in the direction of environmentally friendly and energy-saving. Environmentally friendly rubber plate valve, balance valve and centerline butterfly valve, metal-sealed butterfly valve is gradually replacing the low-pressure iron gate valve. The sea of urban buildings need to use the valve is mostly balance valve, soft seal gate valve, butterfly valve.

Metal-sealed butterfly valves, horizontal balancing valves, and directly buried ball valves are required in the countryside and urban heating systems to address pipeline hydraulic disorders and achieve energy savings and heat balance.

8, environmental protection applications valves, environmental protection systems in the sea, the water supply system is mainly required to use the center line butterfly valves, soft sealing gate valves, ball valves, exhaust valves (used to exclude the air in the pipeline). Sewage treatment system mainly need to use soft seal gate valve, butterfly valve.

9号气阀，城市燃气占据整个天然气市场的22％，阀门用量大，其类型也更多。主要需要球阀，插入阀，减压阀，安全阀。

10个管道应用阀门，远程管道主要用于原油，成品油和天然气管道。这种类型的管道需要使用大部分阀门为锻钢三体全通球阀，抗硫板闸阀，安全阀，止回阀。
