Market prospect analysis of pneumatic operated valves in China

Pneumatic operated valve is a product with low profit margin, and the market competition is very fierce. The distribution of valve market is mainly based on the construction of engineering projects. The largest users of valves are petrochemical industry, electric power department, Metallurgical Department, chemical industry and urban construction department. Gate valve, globe valve and check valve of API standard are mainly used in petrochemical industry; The power sector mainly uses high-temperature pressure gate valve, globe valve, check valve and safety valve for power station, and low-pressure butterfly valve and gate valve for part of water supply and drainage valve; Stainless steel gate valve, globe valve and check valve are mainly used in chemical industry; Metallurgical industry mainly uses low pressure large diameter butterfly valve, oxygen globe valve and oxygen ball valve;

Low pressure valves are mainly used in urban construction departments. For example, large diameter gate valves are mainly used in urban water pipes, midline butterfly valves are mainly used in building construction, and metal sealed butterfly valves are mainly used in urban heating; Flat gate valve and ball valve are mainly used in oil pipeline; Stainless steel ball valve is mainly used in pharmaceutical industry; Stainless steel ball valve is mainly used in food industry. Pneumatic valves are widely used in water treatment industry, mainly low-pressure valves, such as butterfly valve, gate valve and check valve. It is understood that there are more than 2000 valve enterprises with a certain scale in the market, most of which are distributed in Jiangsu, Zhejiang and Central Plains. Due to the relatively low technical requirements of products, the competition is more intense.

On the one hand, China's valve products are facing good development opportunities. With the transfer of oil development to inland oilfields and offshore oilfields, and the development of power industry from thermal power below 300000 kW to thermal power, hydropower and nuclear power above 300000 kW, valve products should also change their performance and parameters according to the changes of equipment application field. Urban construction system generally uses a large number of low-pressure valves, and develops to environmental protection type and energy-saving type, that is, from low-pressure iron gate valve used in the past to environmental protection type rubber plate valve, balance valve, metal seal butterfly valve and midline seal butterfly valve. With the development of oil and gas transportation engineering, a large number of flat gate valves and ball valves are needed. The other side of energy development is energy saving, so from the aspect of energy saving, we should develop steam trap and develop to high parameters of subcritical and supercritical.

The construction of power station is developing to large scale, so large diameter and high pressure safety valve and pressure reducing valve are needed, and quick opening and closing valve is also needed. In order to meet the needs of the whole project, the supply of valves has developed from single variety to multi variety and multi specification. There is a growing trend that all the valves required for an engineering project are provided by one valve manufacturer.
