Ball Valve

A Ball valve is an excellent choice for opening and shut-off. Not only are they durable, but they can remain fully functional even after years of being unused. Sedelon® specializes in producing Ball valves that adhere to the API standard, which we refer to as API Ball valves. Additionally, based on varying design specifications, we also offer DIN Ball valves.
While they may not provide precise control, Ball valves are occasionally utilized for throttling purposes, enabling rapid shut-off. The V-port Ball valve, which can be categorized as a control valve, exhibits superior regulation capabilities. These valves are ideally suited for handling fluids such as fiber, fine solid particles, and slurry media.
Ball valve bodies can be constructed from various metals, including Forged Steel, Stainless Steel, Alloy, Bronze, Cast Steel, and Carbon Steel. Sedelon® specializes in producing Forged Steel Ball valves in accordance with API 602 standards and Stainless Steel Ball valves according to API 603 standards, which we refer to as API 602 Forged Steel Ball valves and API 603 Stainless Steel Ball valves, respectively. Alternatively, the bodies can be made from non-metal materials, such as Ceramic, which offers resistance to erosion, wear, cavitation, and oxidation.
Additionally, there are special materials used for Ball valves, including Special Alloy, Special Steel, and Hastelloy. For media that is highly corrosive, Duplex Stainless Steel Ball valves or Super Stainless Steel Ball valves are typically chosen to address these challenges, as they perform well in corrosive environments.
Ball valves can be installed in two configurations: Top Entry and Side Entry. Top Entry Ball valves allow for easy removal, repair, and replacement of the ball.
The body of Ball Valves can be either integral or modular in design, and they are manufactured to meet ANSI and API standards. Ball valves are highly versatile, capable of enduring pressures up to 1000 bar and temperatures as high as 752°F (500°C), depending on their design and material composition.
Sedelon offers a range of valves tailored to different operating conditions, particularly varying temperatures. For high temperatures, we provide High Temperature Ball valves, while for low temperatures or cryogenic applications, we offer Low Temperature/Cryogenic Ball valves. Jacket Ball valves are used to minimize temperature loss in the line fluid. Additionally, for high temperature environments, High Nickel Alloy Ball valves are an excellent choice. Under high pressure conditions, Sedelon's High Pressure Ball valves are ideal solutions.
Based on the type of connection, Ball valves can be categorized into Screwed, Flanged, and Welded varieties. Welded Ball valves can be further subclassified into Butt Weld, Socket Weld, and Fully Welded types.
A Full Bore Ball valve features an oversized ball with a hole that matches the pipeline's diameter, minimizing fluid resistance and facilitating easy pipe cleaning. In contrast, a Reduced Bore Ball valve has a smaller flow passage than the pipeline, reducing flow rate.
For larger sizes and higher pressures, a Trunnion Mounted or Fixed Ball valve is suitable. A Floating Ball valve operates differently; during normal fluid flow, the ball floats slightly downstream.
Ball valves are easy to operate, typically controlled by a hand lever, hence known as Manually Operated or Hand Lever Ball Valves. When a significant starting force is required, Gear Operated Ball valves are preferred for effortless operation, especially for larger valve sizes. Additionally, some Sedelon Ball valves incorporate pneumatic actuators (Pneumatic Ball Valves) or electric motors (Electric Motor Ball Valves) for operation.
Ball valves can feature more than two ports, with Three-way Ball valves offering L-shaped and T-shaped ports for different flow directions. Four-way Ball valves sometimes have ports shaped like an "X."
Ball valves up to 2 inches in size are commonly designed as two-piece or three-piece constructions (Two-piece or Three-piece Ball Valves).
In today's world, environmental protection is a top priority, and Sedelon takes this into account. Our Low Emission and Low Leakage Ball valves effectively prevent medium leakage and emissions, benefiting the environment. With ISO 15848-1:2006 Fugitive Emission Test Certification, Sedelon produces Fugitive Emission Ball valves to contribute to environmental conservation.
