The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, oil, liquid metal and radioactive media. The demand for valves is on the rise, and energy demand in developing countries is the main factor driving the demand for valves. At present, several types of valves with large demand are: ball valve, globe valve, safety valve, gate valve, butterfly valve, regulating valve and check valve.
Oil refining equipment, most of the valves used in oil refining equipment are pipeline valves, which are mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, etc. Among them, gate valve demand accounts for about 80% of the total number of valves.
02.Environmental protection industry
In domestic environmental protection systems, water supply systems need to use centerline butterfly valves, soft-sealed gate valves, ball valves, and exhaust valves (for removing air from the pipeline), and sewage treatment systems require soft-sealed gate valves and butterfly valves.
In the metallurgical industry, the alumina industry requires the use of wear-resistant slurry valves and regulating traps. Steelmaking industry needs metal-sealed ball valves, butterfly valves and oxidation ball valves, globe valves and four-way reversing valves.
04.Marine energy extraction
With the development of offshore oilfield development, the amount of valves required for its marine energy development has gradually increased. Marine energy extraction requires ball valves, check valves, and multi-way valves.
05.Food and pharmaceutical industry
The industry mainly uses stainless steel ball valves, sanitary ball valves and butterfly valves. Among the above 10 categories of valve products, the demand for general-purpose valves is relatively large, such as instrument valves, needle valves, needle globe valves, gate valves, globe valves, check valves, ball valves, and butterfly valves.
06. Rural and urban architecture
Low pressure valves are generally used in urban construction systems, and they are currently developing towards environmental protection and energy saving. Environmentally friendly rubber plate valves, balance valves, centerline butterfly valves, and metal-sealed butterfly valves are gradually replacing low-pressure iron gate valves. Most domestic urban buildings require valves such as balancing valves, soft-sealed gate valves, butterfly valves, etc.
07.Rural and urban heating
In the urban heating system, a large number of metal-sealed butterfly valves, horizontal balance valves and direct-buried ball valves are needed. Because of these valves, vertical and horizontal hydraulic imbalances in the pipeline are solved to achieve the goals of energy saving and thermal balance.
The construction of power stations in our country is developing in a large-scale direction, so large-diameter and high-pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency blocking valves and flow control valves, and spherically sealed instrument globe valves are required.
09. Gas valve
City gas accounts for 22% of the entire natural gas market, and the demand for valves is very large, and there are many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve.
10. Pipeline transportation
The pipeline’s fluids are mainly crude oil, refined oil and natural gas. The valves that require a large amount of such pipes are forged steel three-body full-diameter ball valves, sulfur-resistant flat gate valves, safety valves, and check valves.
