What is a ball valve?

The Kal Valve, one type of quarter of the rotary valve, is literally a ball located in the passage through which the liquid flows. The ball has through the hole that the valve opens and closes. When the ball is placed so that the hole runs in the same direction as the passage, the liquid simply flows and the valve is open. The ball can also be placed so that the hole is perpendicular to pass so that the liquid cannot pass and the valve is closed. It is controlled from the outside, often with a handle that turns back and forth to open and close the valve.

The basic version described above is a two -way valve. This type has a ball bored one, a straight pass that creates two holes: one on each side, input and output. The Kalský valve can also be a three -way valve if the third hole is partially bored through the ball until it fulfills the main hole and creates T. The three -way valve can turn off one or all three passages connects.

EDEM The nature of this valve does not work well in situations where you need a fine valve check, such as a valve that controls the throttle in the car. It works very well for situations where the flow needs to be completely off, such as the shut -off valve on the main water pipe in the house. Also, the Kall valves do not tend to develop problems unless they are used for a long time; They will still work if necessary.

There are three different types of ball valve. The entire port valve does not offer any flow limitation, which means that when it is open, the liquid can flow freely through it. This is achieved by increasing the ball than the size of the passage, so the hole can be of the same size as the passage. The standard ball valve does not have an excessive ball and as a result the hole is one size less than the passage.This creates a small amount of flow restrictions when the fluid passes. On the other hand, a reduced port port has a smaller ball and an even smaller hole that creates a significant flow limitation when KAPalina passes through it.
