Do you know how many types of ball valves are there? If not, in this article, I have explained everything you need to know about ball valves, such as what is a ball valve, its advantages, and its types.
What is a Ball Valve?
A ball valve made up of a valve plate is something that is attached to a big sphere with a hollow tube that is the same size as the inner diameter of the pipe being used. With a ball rotation, the valve offers the complete conduit or wide-ranging bore needed for unobstructed passage of the liquid and excavators in the normal direction. Furthermore, they are more resistant to contamination than most other valves, making them a good choice for contaminated media applications.
Ball valves may also be utilized as a control valve in certain cases, depending on the configuration. This use is less frequent than other kinds of control valves due to the comparatively poor precision with which the flow rate can be controlled compared to other control valves. However, there are certain benefits to using a valve in this situation. For example, even when the medium is contaminated, it still maintains a good seal.
The Advantages of Ball Valves Casting
When compared to other kinds of valves, ball valves have several distinct benefits, including:
- Designs that are compact and cost-effective
- Fast shut-off speeds are available in four variations.
- High-pressure, high-volume, and high-temperature applications that have long-term durability.
- Less susceptible to rust or damage
- Long service life
- Durable and flexible to a larger extent
What are Common types of ball valves?
- Mounted Ball Valve (threaded)
The mounted ball valve provides a solution to these problems caused by excessive pressure applied to a drifting ball valve in a closed position. An American ball valve with a small spindle, known as a trunnion, is installed in the body of a mounted American ball valve. The ball and the vapor are integrated into a single element with this design. The ball is supported by two floated or spring-loaded seats.
The design of the installed ball valve necessitates a reduced working torque. As a result, the size of the actuation, as well as the total cost of the valve, are both decreased. As the volume and stress class of the valves grow, the cost differential becomes more significant.
- V port ball
V-port ball valves are distinguished only by their seat form or their ball shape, which is denoted by the V. The V control valve allows you to have more control over the slamming shut of the valve. This kind of flow has a flow characteristic that is very similar to linear. Because of the high velocities of the fluids that are utilized with so many ball valves, the developers were obliged to put prepared with the more realistic context for them, as these kinds of chemicals may rapidly destroy a normal valve.
Flanged ball valves are distinguished by the kind of connection that they use. The ports are linked to a pipe system via flanges, which are often built-in lines with a certain standard in order to avoid confusion. Due to the fact that they are usually designed with a full bore, these valves have a high flow rate.
While selecting a flange ball valve, it is important to consider the pressure rating and the flange compression class, which specifies the maximum pressure this connection type can maintain. Ball valves with two, three, or four ports, that can be certified for particular media, that have an ISO-top, and everything else that a normal quarter-turn valve might have is all features of this kind of valve, plus more. Stainless steel, steel, and cast iron are the most common materials used to construct them.
When it comes to their appearance, Vented ball valves are almost identical in appearance to the conventional 2-way ball valves. The most significant distinction is that the outlet port vents to the outside environment when the switch is in the closed position. This is accomplished by drilling a tiny hole in both the ball and the valve’s body.
When the valve is closed, the holes align with the output port, releasing the pressure. A good example of this is in compressed air systems, where depressurization creates a safer working environment for the operators. Due to the design, these valves seem to be two-way ball valves on the surface; however, they are three-way and two-way.
So, these are the types of ball valves.
