ball valve

A ball valve is one of the most common types of valves used in plumbing systems. It is a type of shut-off valve that uses a rotating ball to control and regulate the flow of liquids or gases. Ball valves are usually installed in pipelines where there is a need for frequent on/off operations, like controlling water flow from fixtures such as faucets, toilets, and showers. Ball valves are designed with two openings: an inlet and an outlet port. As the lever attached to the top of the valve is turned, it rotates the internal ball within its seat which either seals off or allows fluid to pass through.

Ball valves can be found in various sizes ranging from 1/4″ all up to 8″. They are commonly manufactured out of brass, stainless steel, plastic or other metal alloys depending on their application requirements. These materials provide strength and durability while also resisting corrosion caused by exposure to moisture or chemicals carried by liquid media passing through them.

Ball valves offer several advantages over traditional gate style valves including ease-of-use due to its simple design; better sealing capability due to its tight fit between the stem seal and body; greater resistance against corrosion since there are no threads exposed inside; lower pressure drop across them compared with other designs – resulting in less stress on downstream components; faster operation times for opening/closing cycles when compared with gate valves; reduced maintenance costs since they require only occasional lubrication for smooth performance; higher temperature ratings than most butterfly styles – making them suitable for use with hot liquids such as steam lines etc.; good visual indication because you can clearly see if it’s open or closed just by looking at it (especially useful when dealing with hazardous fluids) etc..

When selecting a particular type of ball valve however, make sure that you choose one that fits your specific application requirements properly – keeping factors such as size & type material (body & internals), pressure rating (max working pressure), temperature range compatibility etc., into consideration before making your purchase decision so that you don’t end up buying something unsuitable down the line! Also remember not forget any extra accessories like handles & caps needed along with this product during installation time(if necessary). Last but not least – always consult professional plumbers before attempting any kind of DIY projects involving these devices!
