Excerpt:

Hard seal butterfly valves are widely used in all kinds of harsh industrial environments due to their excellent adaptability. It can reliably cope with extreme temperatures (from hundreds of degrees Celsius for high-temperature steam to low temperatures in cold regions), adapt to a variety of pressure levels (from medium and low pressure for water supply and drainage to high pressure for chemical processes), and be compatible with a variety of media (including gases, liquids, weakly corrosive solutions and materials containing solid particles), ensuring the sealing safety of piping systems and stable operation under various working conditions.

Hard seal butterfly valveIt has a wide range of applications in industrial settings, and its working environmental conditions have the following remarkable characteristics.

In terms of temperature conditions, hard seal butterfly valves have the adaptability to cope with high temperature environments. In high-temperature steam piping systems, such as steam transport piping in thermal power plants, where temperatures can reach hundreds of degrees Celsius, the hard seal butterfly valve, with its unique sealing material and structural design, can effectively withstand high temperatures, safeguard piping sealing performance, and prevent steam leakage. In addition, it can also work properly in low-temperature environments, such as outdoor piping in cold regions or low-temperature chemical processes, such as low-temperature liquid transportation, hard seal butterfly valves can still maintain excellent performance to ensure the smooth flow of the process.

In terms of pressure, the hard seal butterfly valve is suitable for a wide range of pressure levels. In the medium and low pressure water supply and drainage system, it can freely respond to the pressure of water flow and realize the opening, closing and adjustment of water flow. For high-pressure chemical processes, such as the high-pressure reactor material conveying pipeline in the process of petroleum refining, the hard seal butterfly valve is specially designed and manufactured to withstand tens to hundreds of atmospheric pressure to ensure the safe operation of the pipeline system.

From the type of media, hard seal butterfly valve is suitable for a variety of media. For gas media, such as air, nitrogen, etc., it can control gas flow and cut off airflow. For liquid media, including water, oil and less corrosive chemical solutions, it can achieve reliable sealing. In the medium pipeline containing solid particles, hard seal butterfly valve also performs well, its hard seal structure is not easy to be damaged by particles, can maintain good sealing effect, widely used in mining, metallurgy and other industries of material transportation pipeline.
