What is Ball Valve?

 

In addition to On /Off service, Ball Valves can be used to modulate flow. A ball valve is a  one type of quarter turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through the hole, and the valve is open. However, when the ball is positioned so that the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed. The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve.  90 Degree ball operate by the help of stem which connected with ball and stem connected with handle.

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. Fire Safe Design 2 Way / 3 Way / 4 Way Ball also used in Oil & Gas Sector.

Ball Valve is also called as Tight Shut off, Bi-Directional Valve. As the temperature increases, the pressure capability decreases. PTFE loses strength in higher temperatures. The Ball Valves have PTFE Seats, Seals & Gland Packing and the temperature withstand capacity of GFT is maximum up to 225 Deg. C. Ball Valves are available with Full Port & Regular (Reduce) Port.  A full port ball valve offers no flow restriction, which means that when the ball valve is open, the liquid can flow freely through it. This is achieved by making the ball larger than the passage size, so that the hole bored through it can be the same size as the passage. A standard port ball valve does not have an oversized ball, and as a result the hole is one size smaller than the passageway. This presents a small amount of flow restriction as the fluid passes through the ball valve. A reduced port ball valve, on the other hand, has an even smaller ball and an even smaller hole, which creates significant flow restriction as the fluid passes through the valve.
