Nickel valve is divided into nickel ball valve, nickel gate valve and nickel globe valve. Nickel and nickel base alloy corrosion-resistant valves are widely used in chemical, petrochemical, metallurgical, atomic energy, marine development, power plant desulfurization and other industrial fields to solve the corrosion problems of stainless steel and other metal and non-metal materials, Ensure the long-term safe, reliable and stable operation of pipeline control valve in extremely harsh corrosive medium. It is a very important class of corrosion-resistant metal valve.

Nickel based alloys are widely used in many fields, such as:

1. Ocean: marine structure of marine environment, seawater desalination, mariculture, seawater heat exchange, etc.

2. Environmental protection: thermal power flue gas desulfurization device, wastewater treatment, etc.

3. Energy field: atomic power generation, comprehensive utilization of coal, tidal power generation, etc.

4. Petrochemical Industry: oil refining, chemical equipment, etc.

5. Food field: salt making, soy sauce brewing, etc. In the above many fields, ordinary stainless steel 304 is not competent. In these special fields, special stainless steel is indispensable and irreplaceable. In recent years, with the rapid development of economy and the continuous improvement of industrial level, more and more projects need higher grade stainless steel. With the increasing demand for nickel based alloys in various industries. In 2011, China's nickel based alloy market reached 23.07 billion yuan, with a year-on-year growth rate of 19.47%. Therefore, the development level of the industry is in a steady upward trend.
