Petrochemical Industry: Ball valves are widely used in the petrochemical field, especially in pipeline systems transporting flammable, explosive, or highly corrosive media such as natural gas, crude oil, and liquefied petroleum gas. Their reliable sealing performance ensures stable operation under high pressure and high temperature environments, effectively preventing leaks and ensuring production safety. Ball valves are widely used for media control in key nodes such as refineries, oil and gas field development platforms, and long-distance pipelines.
Power Industry: In the power industry, ball valves are mainly used in boiler systems, cooling water circulation systems, and desulfurization units to achieve media isolation and regulation. Especially in supercritical and ultra-supercritical units, metal hard-seal ball valves, due to their excellent temperature and pressure resistance, have become an indispensable component of high-temperature steam pipelines.
Urban Water Supply and Sewage Treatment: Ball valves also play an important role in urban water supply and sewage treatment systems. Soft-seal ball valves, due to their low opening and closing torque, resistance to jamming, and ease of maintenance, are suitable for clean water, sewage, and liquids containing suspended particles. In municipal water supply networks, ball valves are commonly used as isolation valves on main pipelines. In wastewater treatment plants, they are used for pump station inlet and outlet control, sludge return systems, etc., ensuring the continuity and safety of system operation.
Pharmaceutical and Food Industries: Sanitary ball valves, with their smooth inner walls, lack of dead corners, and ease of cleaning and sterilization, are the preferred choice for process pipelines in the pharmaceutical and food industries. These ball valves are typically made of stainless steel, comply with GMP and FDA standards, and are widely used in applications requiring extremely high cleanliness, such as pharmaceutical preparation, filling lines, and fermentation tank connections.
Other Fields: Ball valves are also widely used in shipbuilding, HVAC, papermaking, metallurgy, and other fields. In marine fuel, lubricating oil, and seawater cooling systems, ball valves provide reliable fluid shut-off capabilities. In central air conditioning systems of large buildings, ball valves are used for zoned control of chilled water and cooling water, improving system regulation efficiency.
