Ball Valve is a kind of quarter-turn valve which utilizes a hollow, perforated and pivoting ball (known as a "ball") to manage flow through it. It's open once the ball's hole is using the flow and closed when the ball valve’s pivoted 90-levels through the valve handle. The handle lies flat in alignment using the flow when open, and it is verticle with respect into it when closed, creating easy visual confirmation from the valve's status.
Shinjo ball valves are durable in most cases try to achieve perfect shutoff despite many years of disuse. They're therefore a great option for shutoff applications (and therefore are frequently chosen over globe valves and gate valves for this function). They don't provide the fine control which may be necessary in throttling applications but they are sometimes used for this function.
