Different Types of Ball Valves

Capable of bi-directional shut-off, our floating valves have excellent sealing performance and are easy to operate thanks to their simple structure.

Designed with smaller actuators, our trunnion ball valves provide ample space within pipelines while proving efficient under rising pressure.

Through their multi-part body, our 3-way valves enable faster assembly, reassembly, and routine maintenance without doing damage to the pipe.

With a smaller design and high flow coefficients, our V-port ball valves present an affordable choice that achieves similar flow rates as larger models.

With a one-piece body structure for added resistance to pipeline loads, our valves are durable and easy to repair thanks to their superb design.

Requiring fewer installation processes and having a simple design, our valves are easier to install for different applications.

Made of durable steel, our valves are made tighter through primary and secondary seal while maintaining their toughness in stressful environments.

As a friction-free model, our rising stem ball valves require little contact to reduce wear and tear and minimize routine maintenance.

Serving pipeline isolation and chemical sampling, our valves block both sides of a working area while bleeding any pressure within piping to guarantee greater safety.

Built to withstand high pressures and stress cracking, our fully welded ball valves are made to last under constant operation.

Industrial Ball Valves 101

Due to the anticipated growth of ball valves in several different projects and industries, the global industrial ball valves market gained USD 8.1 billion in 2020, and now it is projected to reach USD 14.7 billion by 2025. Moreover, increased industrialization and expansion of existing facilities have spurred demand due to technological innovations and boosted industry growth.

There are different types of industrial valves, but the ball valves took 19% of the global revenue share in the previous year. One of the reasons why ball valves are in demand is that they are mainly applied for flow regulation and whenever tight shut-off is needed.

What is a ball valve?

Ball valves belong to the quarter-turn valve family. These valves can make a ninety-degree direction, allowing or stopping media flow through a ball-like tool found inside the valves. They are easy to operate and can guarantee a tight shut-off seal for industrial applications. On the flip side, ball valves should not be used for partial open or close flow applications since the pressure may affect some parts of the valve. Furthermore, industrial metal-seated ball valves are commonly used in chemical plants, mining, and non-refinery settings. These valves are applied in processes that require crucial isolation, high temperature, high pressure, erosion, abrasion, and corrosion. Due to these applications, the need for metal-seated quarter-turn valves has emerged. However, end-users who choose to trust ball valve manufacturers are advised about the valves’ need for fast actuation and restoration.

Ball Valve Components

Basically, ball valves consist of four main parts: body, ball, stem, and seat. Each segment has an important function.

Body

One of the main ball valve parts is its body and it is attached to the pipes in the pipe structure. The body part is the valve’s framework that keeps all parts altogether and keeps the unit safe from external threats and hazards.

Stem

This refers to the shaft segment that connects the inner ball to the handle or actuator. It transfers the motion of the actual quarter-turn force from the handle to the hidden ball part.

Ball

This is the hollow sphere located in the center of the valve and contains a flow path (also known as hole or tunnel) at its center. It will either allow or stop the media from passing through whenever turned.

Seat

This item seats the ball device in the valve, which provides secondary protection from leakage as the valve closes.

Ball Valves Advantages & Disadvantage

Ball valves have their benefits and downsides

Advantages

Ball valves are cost-effective among all valves since they contain a compact and low-maintenance structure that needs no lubrication. Moreover, they have poor throttling features that can cause the seat of a ball valve to erode quickly.

Disadvantages

On the other hand, ball valves have a limited size range. Also, they are not ideal for permanent throttling because once the medium has suspended particles, it can cause abrasion, leakage, wear, and other issues.

What are ball valves used for?

Ball valves are commonly used in the following industries:

Oil & Gas Industry

Ball valves are widely used in the oil and gas industry due to their flow control, easy to repair features and waterproof sealing. Floating ball valves are usually recommended for low to medium pressure, whereas trunnion ball valves are ideal for high-pressure conditions.

Oil and Gas Industry

Cryogenic Ball Valves

This valve has a ball with a Polytetrafluoroethylene body. This type of valve features better flow conditions than globe valves, and they perform ideally when a tight shut-off is required in multiple applications. However, cryogenic ball valves tend to wear out along the seals and around the ball itself. They are mostly preferred in applications that need an unrestricted flow path.

Low-Tamperature

Chemical Ball Valves

Since ball valves are generally used for flow and pressure regulation and shut off for slurries, corrosive fluids, and normal liquids and gases, they are extensively used in the petrochemical and chemical industry.

Chemical Industry

Types of Ball Valves

There are different types of ball valves, and they are chosen for particular applications based on their qualities. You can select them by their ball movement, type of entry, or body arrangement.

Ball Valves by Ball Movement

Initially, customers have to choose between two main design options: trunnion and floating ball. Here are the differences between the two:

Trunnion Mounted

Trunnion ball valves have additional tools to anchor the ball to a specific spot, serving larger and higher-pressure valve applications. However, they are more pricey than floating ball valves.

Floating Ball Valve

Floating ball valves, usually known as float ball valves, use a non-anchored ball that drifts into place or floats slightly downstream into the seat, which provides a tight seal.

Ball Valves by Entry

You can select ball valves by their type of entry.

Top Entry

Ball valves that assemble their ball from the top side part are called top entry ball valves. These are similar to globe valves with body and bonnet, except the trim part utilizes a ball type. Also, they comprise one single body and are usually made from casting metal.

Side Entry

Side entry ball valves assembled their ball from the side part. They are typically assembled in two or three pieces. Each part of the body is assembled by a bolt or stud, just like joining two pieces of flanges.

Ball Valves by Body Arrangement

You can choose ball valves by their type of body arrangement.

Split-body Ball Valves

Split body ball valves are well suited for highly abrasive and corrosive fluids. They can be either two-piece or three-piece bodies designed for easy maintenance, thanks to their body structure. Also, split-body ball valves components can be replaced quickly and efficiently.

Rising Stem Ball Valves

Rising stem ball valves are mostly the choice of the oil and gas industry for applications requiring a mechanically energized metal or soft seat to prevent losses from process contamination or material leakage. Also, they are ideal for frequent cycling.

Multi-way Ball Valves

Multi-way ball valves are versatile and are used for various purposes. In shipping, for instance, they ensure the seamless switching of alternative fuels. On the other hand, at the production of fine chemicals, they are used within the production lines of the cosmetics or pharmaceutical industry.
