What are the new trends in chemical valves?
"Peaking and neutrality of carbon" is a profound transformation of a socio-economic system. With the dual carbon goal, the domestic chemical industry is quietly undergoing changes and new layouts. The demand and characteristics of valves in the chemical industry are talked about in this article. Grasp the technological change trend of the valve's application, and provide a reference for the technological innovation of valve enterprises.

1. The chemical industry and valves
The chemical industry involves many fields such as oil refining, metallurgy, energy, environment, and coal chemical industry, and its products are widely used. Since the 13th Five-Year Plan, the chemical industry has responded to the call of low-carbon chemicals and gradually upgraded and transformed into fine chemicals, maintaining steady development. The current industry's annual market size has exceeded 6 trillion RMB.

Valves used for the chemical industry have a wide application. Commonly used valves include gate valves, globe valves, plug valves, plunger valves, ball valves, butterfly valves, check valves, diaphragm valves, and pinch valves. Among them, there are three types of valves which are used most, including gate valves, globe valves, and check valves. In various chemical plants, investment costs for valves account for 7 to 10% of the total investment costs.
2. Six major needs for valves under the green chemical industry
The concept of the green chemical industry has penetrated into the various processes of chemical industry production, and profound changes have taken place in the entire chemical industry ecology, which has also brought new development opportunities to the valve industry.
·The increasing amount of valves in natural gas gathering and transportation
Under the dual carbon goal, natural gas, as an important representative of clean energy, has received a golden period of development. China's natural gas market is in a period of vigorous development, and many projects of replacing coal with gas and oil with gas are continuing to advance; the market demand space is very great. As increase exploration and development of the four major natural gas production bases in Sichuan, Xinjiang, Ordos, and sea areas, natural gas production and the construction of gathering and transportation systems will maintain a relatively rapid growth rate, and demand for natural gas gathering and transportation valves will continue to increase.
·The hydrogen valve market
Hydrogen fuel will have major breakthroughs in technologies and applications. Hydrogen chemical industry will have a breakthrough and a rapid growth period. New energy vehicles, industrial green hydrogen, hydrogen refueling stations and hydrogen storage tanks will have more demand for valves.

·The promising prospect of LNG receiving station valves
With the in-depth advancement of replacing oil with gas, the application of LNG in ships and heavy trucks will accelerate, and the technology research and development prospects for LNG receiving terminal valves are very promising.
·Intelligent chemical valves becoming a trend
Green design and smart manufacturing are increasingly referring to the schedule of chemical production and manufacturing. Smart chemicals represented by smart factories and smart chemical management will be valued by more and more enterprises. In the petrochemical field, the development goals of Internet plus, digitalization of pipeline construction, and intelligent operation in the field of pipeline transportation are put forward. In this context, the design and demand for smart valves will naturally increase.
 ·The demand for nuclear valves continuing to rise
The carbon neutral strategic goal is expected to accelerate the normalization of China's nuclear power construction, and the demand for nuclear-grade butterfly valves and ball valves brought about by nuclear power construction will continue to rise.

It should be noted that with the continuous upgrading of nuclear energy technology, the requirements for anti-seismic, anti-radiation, anti-electromagnetic interference and other performances on ball valves and butterfly valves used for nuclear power are becoming more and more stringent.
·The increasing demand for methanol valves
Methanol is low-carbon energy and has a good development prospect in the context of the global energy crisis and environmental pollution. With the deepening of the dual-carbon strategy, methanol's energy demand will be released.

4. Summary
In general, the layout of the chemical industry under the policy of dual carbon is undergoing profound adjustments, and there is an obvious demand for high-performance, high-efficiency, and high-quality valves. This also indicates that the valve industry has become a trend of the arrow being on the bow-poised to strike. It is recommended that the valve industry should actively adapt to the situation, embrace new changes in the valve market, strengthen independent technological innovation, serve the development needs of the chemical industry, and promote its own industrial upgrading.
