Application Fields
The wafer ball valve is mainly used to control and regulate fluid flow, pressure and temperature in industrial automatic control systems. It controls flow for boilers, air‑conditioning, refrigeration systems, gas and water pipelines. It is widely applied in petroleum, chemical, power generation and water treatment industries for flow and pressure regulation. It also handles various liquids such as gasoline, diesel oil, grease and lubricating oil.
