1. Valves for petroleum installations
(1) Oil refining device. Most of the valves used in refinery units are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, and steam traps. Among them, gate valves account for about 80% of the total number of valves. 3% to 5% of investment);
(2) Chemical fiber device. Chemical fiber products mainly include polyester, acrylic and vinylon. The ball valve and the jacket valve (the jacketed ball valve, the jacketed gate valve and the jacketed shut-off valve) of the valve to be used;
(3) Acrylonitrile device. The device generally needs to use the valve produced by the scale, mainly for the gate valve, the stop valve, the check valve, the ball valve, the steam trap, the needle-shaped stop valve, the plug valve, wherein the gate valve accounts for about 75% of the total valve;
(4) Synthetic ammonia unit. Because of the different synthetic ammonia and purification methods, the process flow is different, and the technical functions of the required valves are also different. At present, domestic ammonia plants mainly need 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;
2. Application valves for hydropower stations.
The construction of power stations in China is developing in the direction of large-scale, so it is necessary to use large-diameter and high-pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency blocking valves and flow control valves, and spherical sealing instrument stop valves.
3. Metallurgical application valves.
In the metallurgical industry, the behavior of alumina mainly requires the use of an anti-abrasive slurry valve (in the flow-type shut-off valve) and the adjustment of the trap. The steelmaking industry mainly needs metal sealed ball valves, butterfly valves and oxidized ball valves, cut-off flash and four-way reversing valves;
4, marine application valve
With the development of offshore oilfield exploitation, the amount of valves required for ocean flat hair has also gradually increased. The offshore platform needs to use a shut-off ball valve, a check valve, and a multi-way valve;
5, food and medicine application valve
The industry mainly needs stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves. Among the above 10 types of valve products, the demand for general-purpose valves is relatively large, such as instrument valves, needle valves, needle-shaped globe valves, gate valves, globe valves, check valves, ball valves, butterfly valves;
6, rural, urban construction application valve
The urban construction department generally adopts low-pressure valves and is currently developing in the direction of environmental protection and energy conservation. Environmentally friendly rubber plate valves, balancing valves, mid-line butterfly valves, and metal-sealed butterfly valves are gradually replacing low-pressure iron gate valves. Most of the valves used in urban construction in the country are balance valves, soft seal gate valves, butterfly valves, etc.;
7, rural, urban heating valves
In the urban heat generation system, a large number of metal sealing butterfly valves, horizontal balancing valves and direct-buried ball valves are needed, and such valves are used to solve the problem of longitudinal and lateral hydraulic imbalance of the pipeline, thereby achieving the purpose of energy saving and heat balance.
8, environmental protection application valve
In the domestic environmental protection system, the water supply system mainly needs the midline butterfly valve, the soft seal gate valve, the ball valve, and the exhaust valve (used to remove the air in the pipeline). Sewage treatment systems mainly need soft seal gate valves and butterfly valves;
9, gas valve
City gas accounts for 22% of the entire natural market, and the valve usage is large, and there are many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve;
10, pipeline application valve

Long-distance pipelines are mainly crude oil, finished products and natural pipelines. The valves that require a large amount of such pipelines are forged steel three-piece full-bore ball valves, sulfur-resistant slab gate valves, safety valves, and check valves.
