A Brief Introduction to Ball Valves

Valves are generally partitioned into several types to reach their particular specifications and functions. Now, a profound gander at the ball valve is taken here. Similar to other valves, a ball valve is usually used to control the stream. The featured part is a spherical disk, which controls the move through it.

And there is an opening or port in the sphere. In fact, the two finish of the valve determines a lot. When the two ends of the valve in line, stream will happen. And when the valve is closed, the opening is perpendicular to the ends of the valve, and stream is impeded. During this process, the handle or switch will do a great favor being inline with the port position.

Basing on particular specifications and easy operation, ball valves are used extensively in industry as a result of versatility and wide range of supporting pressures and temperatures. And sizes typically range from 0.5 cm to 30 cm. Generally speaking, materials for the body are metal, plastic or metal with a ceramic center. And the ball is often chrome covered to enhance the durability and make the valve work perfectly at shutoff.

According to the perspective of body types, they are single body, three piece body, split body, top entry and welded. It is to say that the classification is based on the number Van bi điều khiển khí nén of pieces of the valve. Though there are different types of valves, the operation is similar. And according to the perspective of the bore of the ball mechanism itself, there are also many styles.

They are a full port, reduced port, V port, trunnion and cavity filler ball valve. What’s more, manually operated ones can be closed quickly. And some are outfitted with an actuator that may be pneumatically or motor operated. Those valves are usually outfitted with a positioner. By doing this, it is easy for it to transform the control signal into actuator position and valve opening accordingly. For example, multi-port ball valves are generally with 4 ways, or more. They are also commercially available. And for the driving air-powered motors from forward to reverse, the operation is performed by rotating a single switch 4-way ball valve. What else, one piece ball valves are almost always reduced bore, which are relatively inexpensive and generally are throw-away. And two piece ones are generally slightly reduced (or standard) bore, they can be either throw-away or repairable.

In words, some general ideas about the ball valves have come into your mind, I suppose. Expectation they would be generally used in order to work on the industry, as well as our daily life.
