Ball valves are one of the most common valve types used in both residential plumbing and industrial processes. They are typically used for basic on/off service. For this reason they are referred to as shutoff valves, isolation valves, or stop valves. They are operated with a simple 90 degree turn (qurter-turn) of a sphere shaped obstructor or “ball”. This ball has a hole through it to allow flow to pass through in one position, but stops the flow in the when rotated 90 degrees.
Above brief Ball Valve is a basic two-way valve. This ball valve has a single, straight passageway bored through the ball, making two openings: one on each side, an inlet and an outlet. A ball valve can also be a three-way valve if a third hole is bored partially through the ball, until it meets the main hole, in a shape T or L. A three-way ball valve can shut off one or all of the three passageways it connects. Four Way Ball Valve also used with Double L/X Port for Air/Co2/Nitrogen/Gas Dryer application.
