The Main Application Fields of Valves.

• Valve for petroleum equipment;

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 and drain valves. Among them, 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 of the unit);

• Chemical fiber equipment, chemical fiber products are mainly polyester, acrylic, vinylon three categories. The ball valve and jacketed valve (jacketed ball valve, jacketed gate valve and jacketed globe valve) are required。
• Acrylonitrile unit. The device generally needs standard produced valves, mainly gate valve, stop valve, check valve, ball valve, drain valve, needle type globe valve, plug valve, in which gate valve accounts for about 75% of the total valve volume
• Ammonia plant. Because of the different synthetic ammonia and purification methods, the process flow is different, and the technical functions of the required valves are also different. At present, the domestic ammonia plant mainly needs gate valve, globe valve, check valve, drain valve, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature and low temperature valve
• Hydropower stations with large diameter and high pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency stop valves and flow control valves, globe sealed instrument globe valves
• The wear-resistant slurry valve (in flow stop valve) and regulating drain valve are mainly needed for metallurgical application valve and alumina behavior in metallurgical industry. The steel-making industry mainly needs metal sealed ball valve, butterfly valve and oxidation ball valve, stop flash valve and four-way reversing valve
• With the development of offshore oilfield exploitation, the number of valves required for marine horizontal development is gradually increasing. The offshore platform needs shut-off ball valve, check valve and multi-channel valve
• Food and medicine application valve, the industry mainly needs stainless steel ball valve, non-toxic all plastic ball valve and butterfly valve. Among the above 10 kinds of valve products, the demand for general valves is more, such as instrument valve, needle valve, needle type globe valve, gate valve, globe valve, check valve, ball valve and butterfly valve
