 Valves are widely used in various industries, such as oil, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, fire protection, machinery, coal, food and other industries. At present, on the market, the most-used and most common valves are ball valves, globe valves, gate valves, safety valves, followed by butterfly valves and control valves. The third one is check valves. Pressure reducing valves, drain valves and steam traps rank forth. Shutoff valves and diaphragm valves are sixth and the last one is plug valves, plunger valves and other valves. Compared with ball valves, globe valves, gate valves and safety valves, the rest of the valves above take a small part of production and their total output account for 36.4% in all valve production.

Compared with other fields, more kinds of valves are used in machinery, metallurgy, petrochemical, chemical, urban construction and so on. Especially for machinery, almost all types of valves are applied in this industry. Safety relief valves are mainly used in chemical while butterfly valves are more used in petrochemical and metallurgy. For diaphragm valves, they are mainly applied in metallurgy, electric power and chemical. Slightly different from diaphragm valves, check valves are mainly used in metallurgy, chemical and petrochemical. Globe valves are used in petroleum and chemical, and besides these two industries, ball valves are also used in metallurgy. Shutoff valves and control valves have more application fields relatively, the first one is mainly used in metallurgical, petrochemical, chemical and electric power and the second one is applied in chemical, metallurgy, electricity and food. Drain valves are widely used in petrochemical and chemical while gate valves are mainly used in chemical, electric power and urban construction. As for plunger valves, they are mostly used in petrochemical and metallurgy and plug valves are more applied in chemical and metallurgy. For petrochemical, chemical and metallurgy these three industries, it is pressure reducing valves that widely used in. And steam traps are more applied in chemical and petrochemical.

The continuous development of various industries requires more valve enterprise to research and produce high-end products to meet the line of international standard, thus can advance the whole valve industry to develop in the direction of high and new technology.
