Ball flaps are used in both household and industrial plumbing and in many industries. Used to change the flow of water, regulate the flow or close the water in the event of an emergency, dampers are a valuable component of any plumbing system. Wastewater treatment centers, drug manufacturers, chemical plants, car production depend on valves for the management and diversion of liquids and gases. Ball flaps are made of a wide variety of materials: brass, plastic, cast iron, stainless steel. Ball flaps are the most commonly used shut-off valve. Popular for their speed, reliability and durability, ball flaps are widely used in residential and industrial premises to turn the water on and off without pressure drops. The ball in the valve creates a watertight seal that prevents the liquid from escaping. Due to this sealed sealant, they are also common in the field of natural gas and chemistry. Ball valves should be used only to open and close the passage of fluid. They are not intended for throttling, as this can damage the rotating ball and potentially damage the valve. 

Ball flaps are able to withstand high pressure and powerful flows. They do not need to be lubricated or maintained, like some other dampers. Ball flaps are cheaper than many other valves that are used for similar purposes.
