Dombor supplies various industrial ball valves to meet different application demands. Regardless of high or low-temperature applications, industrial ball valves manufactured by Dombor are commonly used in these below industries.
DomBor Valve, with its experienced specialists, specializes in manufacturing industrial valves and provides technical support and one-stop solutions for the global market.
Due to the anticipated growth of industrial 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. While industrial ball valve suppliers Dombor manufactures various ball vales for your application need.
There are different types of industrial valves, but industrial ball valves took 19% of the global revenue share in the previous year. One of the reasons why industrial ball valves are in demand is that they are mainly applied for flow regulation and whenever tight shut-off is needed. Industrial ball valves still could be sorted by bronze valves and brass valves.
Industrial 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, industrial 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 industrial ball valves manufacturers are advised about the valves’ need for fast actuation and restoration.
Basically, industrial ball valves consist of four main parts: body, ball, stem, and seat. Each segment has an important function.
One of the main industrial 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.
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.
This is the hollow sphere located in the center of the industrial ball 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.
This item seats the ball device in the valve, which provides secondary protection from leakage as the industrial ball valve closes.
Manufactured by certificated industrial valve manufacturer Dombor, ball valve still has its advantages and disadvantages because of objective factors.
Industrial ball valves are cost-effective in all valves because they contain compact and low-maintenance structures that do not require lubrication. Most industrial ball valves are made of metal and corrosion-resistant materials, which is why they can withstand extreme conditions and extend their service life. Industrial ball valves can also withstand hydraulic shock, strong vibration and extreme flash.
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.
Dombor, as your industrial ball valve suppliers China, custom valves for your business need. There are different types of industrial ball valves, and they are chosen for particular applications based on their qualities. You can select ball valves by their ball movement, type of entry, or body arrangement.
Initially, customers have to choose between two main design options: trunnion and floating ball. Here are the differences between the two:
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 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.
You can select industrial ball valves from us as one of top entry ball valve manufacturers by types of entry.
Industrial 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 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.
You can choose industrial ball valves by their type of body arrangement.
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 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 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.
Lasting througn many years of constant use, DomBor industrial ball valves can withstand various pressures and corrosion. Due to their bubble-tight seal, they are zero-leak and capable of controlling high pressures and high fluid volumes.
