Ball valves are versatile shut-off and control valves used globally in plumbing, HVAC, oil & gas, chemical processing, and water treatment to regulate fluid (liquid, gas, steam) flow by rotating a ball with a bore, providing quick, tight seals for on/off functions and low-pressure drop, ideal for applications needing reliable isolation or quick operation, from home plumbing to complex industrial pipelines. Key Uses by Industry Oil & Gas: Pipelines, refineries, storage tanks for controlling crude oil, gas, and hydrocarbons, even in high-pressure/temp or subsea conditions. Water & Wastewater: Treatment plants, supply lines, irrigation, and plumbing for managing water and chemical flows, preventing backflow. HVAC: Controlling chilled water, hot water, and air in heating, ventilation, and air conditioning systems. Chemical Processing: Handling corrosive chemicals, acids, and steam due to material options like stainless steel. Power Generation: Managing cooling water, feed water, steam lines, and turbine/compressor systems.
