TEN APPLICATION AREAS OF VALVES

A valve is a piping accessory used to open and close a pipeline, control the flow direction, and regulate and control the parameters of the transport medium. It has applications in various industries. Today, let's take a look at the top ten application areas of industrial valves.

 

1. Valves for Petroleum Installations

(1) Oil Refining Device

Most of the valves used in oil refining units are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, among which 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 in the device).

(2) Chemical Fiber Device

Chemical fiber products mainly include polyester, acrylic and vinylon. The ball valve and the jacket valve (such as a jacketed ball valve, a jacketed gate valve, and a jacketed shut-off valve) are used in the chemical fiber device.

(3) Acrylonitrile Device

In general, the device needs scale production valves, mainly gate valves, globe valves, check valves, ball valves, traps, needle-shaped globe valves, cock valves, of which the gate valves account for about 75% of the total number of valves.

(4) Synthetic Ammonia Device

Because the synthesis of ammonia and purification methods are different, the process is different, and the technology of the required valves is 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. 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 shut-off valves.

 

3. Valves for Metallurgical Applications

In the metallurgical industry, the behavior of alumina mainly requires the use of an anti-abrasive slurry valve. The steelmaking industry mainly needs metal sealed ball valves, butterfly valves, oxidized ball valves and four-way reversing valves.

 

4. Valves for Marine Applications

With the development of offshore oil field exploitation, the amount of valves needed for offshore development is also increasing gradually.

Offshore development requires shut-off ball valves, check valves, and multi-way valves.

 

5. Valves for Food and Pharmaceutical Applications

Stainless steel ball valves, non-toxic plastic ball valves and butterfly valves are mainly needed in this industry. Among the above valve products, the demand for general valves is more than others, such as instrument valves, needle valves, gate valves, globe valves, check valves, ball valves, etc.

 

6. Valves for Rural and Urban Building Application

The urban construction department generally adopts low-pressure valves and it is currently developing in the direction of environmental protection and energy conservation. Environmental-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 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 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 Valves

In the domestic environmental protection system, the water supply system mainly needs mid-line butterfly valve, soft sealing gate valve, ball valve and exhaust valve (for eliminating air in the pipeline). Soft sealing gate valves and butterfly valves are mainly used in sewage treatment system.

 

9. Gas Valves

City gas accounts for 22% of the entire market. The valve usage is large, and there are many types. Ball valves, plug valve, pressure reducing valve, safety valve are mainly required.

 

10. Pipeline Application Valves

Long-distance pipelines are mainly for crude oil and finished products. The most commonly used valves for this type of pipeline are forged steel three-body global diameter ball valves, sulfur-resistant flat valves, safety valves and check valves.
