How Water Works Ball Valves Overtook Plug Valves in Superiority

Valves are very important devices that control and direct the flow of liquids and gases by opening and closing various passageways. While there are many valve designs, the ball valve is the most popular member of the quarter-turn valve family. Since its introduction in the early 1960s by A.Y. McDonald and other industry leaders, the ball valve rose in popularity and has now become the valve of choice for most water works applications. Not only does the ball valve surpass other valves with its superior pressure rating and durability, but it is also more functional for the everyday user. 

High-pressure rating
Ball valves are excellent at maintaining and regulating high-volume, high-pressure flow. Because ball valves are extremely durable, they are able to withstand more pressure per unit than other more fragile valves, such as plug and butterfly valves.  

Durability
Ball valves are extremely durable and are built to withstand many years of continuous operation. While plug valves are known to leak after a period of time, ball valves are built with reliable, airtight sealing designed to survive extreme pressure. Unlike the lubricants used with other valves, the superior coating and EPDM rubber seals used on ball valves today is more durable and does not require re-application after years of wear and tear.

Functionality
That ball coating makes the valve extremely easy to operate. Unlike plug valves, ball valves require no additional lubrication other than the coating on the ball, making their maintenance minimal.

Best used for fast-acting, start/stop applications, ball valves only require a 90 degree turn to operate the valve. This quarter-turn function minimizes valve operation time and decreases the possibility of leakage due to continuous usage.
