Ball Valve

Ball valves are designed with a spherical disc, which is the part of the ball valve that controls the flow through it. There is a hole in the middle of the sphere so that when the hole is in line with both ends of the ball valve, the flow will occur. When the handle, which is a 90° turn,  is moved to the close position, the hole is perpendicular to the ends of the valve, blocking the flow. 

Ball valves are commonly used in locations where a shut off valve is needed. They are also available with different end connections and in multiple materials including stainless steel, brass and plastic. The different end connections available are threaded, push fit, compression.
