Control Valve

What is a ball valve? A ball valve, one type of quarter turn valve, is in effect literally a ball placed in a passageway through which liquid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so the hole runs the same direction as the passageway, the liquid simply flows through the hole, and the valve is open. However , when the ball is positioned so that the hole is at right angles to the passage, the liquid cannot pass thru, and the valve is closed. The ball is controlled from outside the valve, often with a handle that's turned ninety degrees, or 1 / 4 turn, backwards and forwards to open and close the valve.

The basic ball valve is a two-way valve. This ball valve has a single, straight passageway bored through the ball, making 2 openings : one on each side, an inlet and an outlet. A ball valve can also be a three-way valve if a 3rd hole is bored partially through the ball, till it meets the main hole, forming a T. A three- way ball valve can shut off one or all of the three passages it connects.

Due to the nature of the ball valve, it does not work well in eventualities in which fine control over the valve is needed, such as the valve that controls the throttle in a car. However , a ball valve works very well for scenarios in which a flow should be totally shut off, for example the shut-off valve on the main water line in your house. Ball valve also don't tend to develop issues if they're not used for long periods ; they'll still work perfectly when needed again.

There are 3 different sorts of ball valve. A full port ball valve offers no flow restriction, meaning that when the ball valve is open, the liquid can flow freely through it. This is done by making the ball bigger 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 in comparison to the passageway. This presents a small amount of flow restriction as the liquid passes thru the ball valve. A reduced port ball valve, on the other hand, has an even smaller ball and an even smaller hole, which creates serious flow limitation as the liquid passes thru the valve.
