Top ten application areas of valves

Valves are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, and occupy a pivotal position in the national economy. Let us look at the specific application areas of the valve.

 

 

1. Valves for petroleum installations

(1) Oil refining equipment. Most of the valves used in oil refining equipment are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, and traps. Among them, gate valves account for about 80% of the total number of valves;

(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;

 

 

2. Valves used in hydropower stations

The construction of power stations in our country is developing towards large-scale, so large-caliber and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency stop valves and flow control valves, and spherical seal instrument stop valves are needed.

 

 

3. Valves for metallurgical applications

 The behavior of alumina in the metallurgical industry mainly requires wear-resistant slurry valves (in-flow stop valves) and regulating traps. The steelmaking industry mainly needs to use metal sealed ball valves, butterfly valves and oxidation ball valves, stop flash and four-way reversing valves;

 

 

4. Marine application valve

With the development of offshore oilfield exploitation, the amount of valves required for its marine flat development 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

This 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 valves is more, such as instrument valves, needle valves, needle globe valves, gate valves, globe valves, check valves, ball valves, and butterfly valves.

 

 

6. Valves for construction applications

The urban construction department generally uses low-pressure valves, and is 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 urban construction in China are balance valves, soft seal gate valves, butterfly valves, etc.;

 

 

7. Valves for rural and urban heating

In the urban heat generation system, a large number of metal-sealed butterfly valves, horizontal balance valves and direct-buried ball valves are needed, because these valves solve the problem of vertical and horizontal hydraulic imbalance of pipelines, and achieve the purpose of energy saving and heat balance.

 

 

8. Valves for environmental protection applications

 In the domestic environmental protection system, 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 sealing gate valves and butterfly valves;

 

 

9. Gas valves

City gas accounts for 22% of the entire natural market, with a large amount of valves and many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve;

 

 

10. Valves for pipeline applications

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-body full bore ball valves, anti-sulfur flat gate valves, safety valves, and check valves.
