In recent years, with the increasing demand for natural gas in the market, the development speed of natural gas filling stations has been accelerated. At present, many provinces in China have issued management measures on gas filling stations, delegating the approval authority for the establishment of gas filling stations, which has further stimulated the development of natural gas filling stations in China. It can be said that the continuous high temperature of natural gas filling demand throughout the country has made gas filling stations a rapidly developing industry.

During the construction of natural gas filling station, many supporting facilities are needed, including high-pressure valves. The rapid development of gas stations has also promoted the development of related industries from some perspectives, and high-pressure valves, as the control and connection equipment that gas stations must have, have become one of the most important accessories of gas stations. In recent years, the state has continuously strengthened the supervision of the safety of gas stations, making high-pressure valves, the most important accessories, become the focus of attention.

In the past, the patents of high-pressure valves were generally abroad, and some valves used at home were also imported. The lack of independent innovation and production capacity has made China difficult in this field. In recent years, economic development has led many enterprises to increase research and development efforts, continue to promote the production of domestic high-pressure valves, and strive to gain a foothold in the high-pressure valve market. At present, China has many comprehensive service companies committed to the natural gas industry, among which Zhejiang special technology valve group Co., Ltd. is one of the professional companies, and natural gas valve is one of the company's main products.

We know that most natural gas filling stations now use compressed natural gas, which is often called CNG. CNG has a very high pressure, so safety is an important factor to be considered in establishing a gas filling station, and the role of high-pressure valves is to control all parts of the gas filling station, so as to ensure safety, such as stop valves, ball valves, check valves in high-pressure valves, Plunger valve and so on are very important components of the gas station. Therefore, the selection and use of high-pressure valves in the gas station is related to the safety and stability of the whole gas station system, and the selection of products must be careful.

Although the high-pressure valve is a small product, its role can not be ignored. Due to the increasing emphasis on safety, more and more gas stations pay attention to safety issues, so the requirements for high-pressure valves are also getting higher and higher. It can be said that high-pressure valves can really escort the improvement of the comprehensive service capacity of gas stations.
