The Ball valve is arguably the most used and popular valve in the industry. And there are good enough reasons behind this. People love to use it because of its variety of unique types and benefits. You may see or use them every day in different applications but never recognize them. Read on to learn everything about ball valves.

The Ball valve is a mechanical device used to control and direct the flow of various substances. In other words, it is a valve that has a ball with a hole at its center that can open, close, and direct the media flow. It controls the flow with a lever and the rotation of the ball. The water bibcock (lever-type) in your house or garden is the best example of a ball valve.

Types Of Ball Valve

Brass Ball valves come in a variety of types with unique features. These types are made depending on many criteria such as:

Body Construction: 1-piece, 2-piece, and 3-piece body. Here, body pieces define that the number of body sections the valve has. For example, a 3-piece ball valve consists of two pipe connectors and the main body.

A number of ports: 2 and 3. The standard type is 2 ports, 1 inlet, and 1 outlet. But the 3 port design allows you to use 2 ports as inlet and 1 as outlet or vice-versa.

Ball Hole Size: Full bore, Reduced bore, and V-shaped. The diameter of a full bore valve is equal to the pipe’s diameter. The reduced bore valve has a smaller hole than the pipe hole. And as the name implies, the ball of the V-shaped valve has a V-shaped design hole.

Ball Design: Floating and Trunnion Mounted. The ball floats inside of the valve in a floating ball valve. And the Trunnion is similar to the floating one but with spring-loaded seats.

Operation: Manual and Electric or Motorized. Most of the ball valves are operated manually. But new types are available with electrical components to operate it automatically.

Ball Access: Side-entry and Top-entry. Entry direction specifies that from which side you can access the interior of the valve.

Ball Valve Parts

A ball valve is made with different types of small components. Here is a summary of regular-type ball valve parts:

Firstly, when you look at it, you will notice a flattened Handle attached to the valve. But sometimes, you will see a spinning handle instead of that sliding handle. The handle has a Nut with a Thrust Washer on the above. These two helps to tighten the handle with the valve. Secondly, right underneath the handle, there is a Gland NutThe gland nut ensures the watertight seal to prevent leakage while the system is on.

In addition, there is a metal rod named Steam that connects the upper mechanism with the Rotary Ball inside of the valve. The rotary ball is a round steel ball with a bore (hole) inside. It’s in the right in the middle of the valve body while the two O-shaped seats surround it on both sides. You can consider the rest you see outside as the valve body. It has two ends one is the inlet, and the other is the outlet.

That is all a regular-type ball valve consists of. However, when it comes to the motorized one, only the upper parts are changes. The electrical component replaces the handle to automate the valve.

How Does A Ball Valve Works?

ball valve manages the flow of the substances and flows direction. The multi-port (3-way) valves can also mix multiple media and send it in different directions. It does this with a brass rotary ball. Let’s see how.

It is a very simple but effective trick. If the valve is closed, the ball hole is set in the opposite direction. When you slide the handle from 0 to 90 degrees, it will rotate the ball also. Therefore, the holes of the ball will meet with the inlet and outlet hole. This will create a path for the media to flow. Finally, the media or substances will flow without any interruption.

Again when you slide the handle in reverse, it will rotate back the ball too. After that, the ball hole will move and seal the drain. As a result, the flow will stop. This is how a ball valve works.

Ball Valve Benefits

Ball valves have a number of distinct advantages over other types of valves. Such as:

1.Supports almost all types of media and ensures reliable sealing. 

2.The structure is pretty simple, so you can easily disassemble and repair it.

3.You can easily operate the valve by simply rotating the handle. Also, it offers quick on-off, which is very helpful in case of emergency.

4. Have a low-pressure drop and a reasonable rate of flow capacity.

5. The chances of corrosion or damage are low so that it will serve you for a long time.

6. Available at low prices.

Uses

The demand for Ball valves is expanding worldwide due to their various forms and excellent benefits. You can use them anywhere from your home’s water bibcock to big industrial pipelines. For example, our daily life applications like washing machines, dishwashers, plumbing systems, outdoor hoses, etc… use ball valves to control water flow. Also, industries such as oil, natural gas, pharmaceutical, manufacturing, vehicle wash systems, chemical, automotive, and many others… use ball valves for their different purposes.

Above all, you have got a crystal clear idea about ball valves. And if you are about to set up a new application or something related to that, you will need ball valves. You have many options but think carefully and choose the right one for your needs.
