About a Ball Valve


Mechanical devices such as ball valves allow you to guide the flow of various substances such as pressure, gas, and liquids. Ball valves online may also regulate the flow of substances such as water.

It is a member of the quarter-turn type of valves family.


  • Low upkeep and maintenance costs.
  • The ability to function efficiently in terms of time and labour.
  • A large number of switch on/off options.
  • There are minor pressure reductions.
  • Minimal leakage in case of normal wear and tear.

Various applications:

Protection against leaks is required in the majority of industrial applications. This is critical for individuals who demand a tight sealed on/off mechanism. Examples of these sorts of applications include solely liquid or gaseous ones, such as the natural gas industry, chemical storage, etc.

Different ball valves may be categorised according to their characteristics, which include:

Based on type of port:

Whole Port Kind: This type has an internal diameter that is the same as the pipe’s inner diameter to which it is linked. The essential advantage of this design is that it has lower frictional resistance. Because it does not hinder fluid flow, it is frequently used in the refining and petrochemical sectors, even though it is more expensive to install because of the higher cost of materials.

Reduced Port Kind: This type has a smaller internal diameter in the centre and a larger internal diameter on the ends, resulting in a more compact design. Consider the following example: a 3″ Ball valve will have a 2″ bore in the middle and a 3″ bore at each end.

Based on the number of pieces

  • Design using a single piece
  • Design with a split piece (two-piece/three-piece)

Based on ball movement

Floating Form: The floating type of ball valve is the most frequent type of ball valve design because the ball inside the valve is of the floating type. It is supported by two seats built of soft elastomeric material to provide a comfortable ride. The quarter-turn is accomplished by the stem attached to the top of the ball.

The ball is retained firmly in position due to this design modification. Suitable for low and high-pressure applications, they have lower operating costs than other types of pumps.

By Arrangement of the Body:

Side entrance, top entry, three-way or four-way, and rising stem type ball valves are the most common classifications used by ball valve online suppliers to classify ball valves based on their body arrangement.

Side-entry Type: The ball and other internal components of this valve are enclosed within the body, and the bonnet is attached to the body on the opposite side of the ball and internal components.

This type of valve is distinguished by having the bonnet cover positioned on the top section of the ball, enabling the removal, assembly and repair of the internal valve parts to be performed with ease.

A 3-way valve has an entry on three/four sides, while flow enters one end and travels through the other ends in different directions, depending on the valve employed.

The rising stem type of ball valve has a stem inserted in the seal, preventing the two sides from coming into contact. This design helps decrease the uneven wear and tear on the seat cushion.

By Type of Material:

Valve manufacturers mostly employ common materials such as carbon steel and stainless steel, alloy steel, bronze, brass, and PVC, and then classify their products according to their application.

Before sourcing and investing in valves, it is critical to understand the temperature ranges they may perform differently from one another. This is the best approach for achieving a better outcome, which is critical for the purpose for which these valves are made.
