Titanium Gr2-Gr5 Electric Ball Valve

Titanium Alloy Overview:

Titanium, despite being highly chemically active, exhibits exceptional corrosion resistance primarily due to its strong affinity for oxygen. When exposed to oxygen, titanium rapidly forms a dense and stable oxide film on its surface. This oxide layer acts as a protective barrier against further oxidation and corrosion. Importantly, this film has the ability to regenerate quickly when scratched or damaged, as long as there is sufficient oxygen available in the environment.

This self-passivating oxide film is crucial for titanium's stability in harsh corrosive environments. It effectively shields the metal from aggressive chemicals, seawater, and other corrosive substances that would otherwise degrade less resistant materials. The protective oxide layer not only enhances the longevity of titanium equipment but also ensures reliable performance in critical industrial applications where corrosion resistance is paramount.

Electric Ball Valve:

A ball valve is a type of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. When the valve is in the closed position, the ball is rotated such that the hole through the ball is perpendicular to the flow openings of the valve body and the flow is blocked. When the valve is open, the hole is in line with the flow openings of the valve body and flow is permitted.

An electric ball valve is operated by an electric actuator, which allows for remote or automated control of the valve's position (open or closed). This is typically achieved through electrical signals, making it suitable for applications where manual operation is impractical or remote control is desired.

Main Connection Sizes (Nominal Diameter DN):

You've listed nominal diameters for connecting titanium valves, indicating their sizes for various applications. These sizes typically range from 15 DN to 250 DN, with specific dimensions such as length (L), outer diameter (D), inner diameter (D1), flange diameter (D2), bolt hole diameter (B), number of bolts (Z-d), height (H), and width (W) specified for each nominal diameter.

Titanium Grades:

Titanium alloys are categorized into various grades, each designed for specific applications based on their chemical composition and properties. Some common titanium grades mentioned include:

Titanium is classified into several grades, each designed for specific applications based on their properties. Here are some common titanium grades:

Grade 1: Grade 1 titanium is the softest grade of titanium, which makes it very formable. It offers a high ductility while still maintaining the necessary impact toughness. This grade is most often used in plates, tubing, piping, and a range of other applications where a higher level of weldability and formability is important.

Grade 2: For slightly stronger metal, there is Grade 2 titanium. It is still very moldable, but has a higher tensile strength. Grade 2 titanium is very widely available, which makes it more affordable than other grades. The common product forms include everything from bar and billet to plate and wire.

Grade 3: Grade 3 titanium is not used near as much as grade 2, but it still has its uses. It is stronger than grades 1 and 2, features good weldability, and extremely high corrosion resistance. It is less moldable than the other 2 grades, but the added strength and resistance make it a good choice for: chemical processing, marine applications and aerospace.

Grade 4: Grade 4 titanium is the strongest pure grade titanium, but it is also the least moldable. Still, it has a good cold formability, and it has many medical and industrial uses because of its great strength, durability and weldability.

Grade 5: Grade 5 is popular in the aerospace industry for aircraft turbines as well as structural components, but it is also used in high-performance engine parts, sports equipment biomedical implants, and more. Common product forms include bar, billet, foil, sheet, seamless pipe, wire, plate and more.

Grade 7: Grade 7 is the most corrosion resistant of the titanium alloys. It features most of the properties of grade 2 pure titanium, but the added palladium helps increase the weldability and formability. It is most commonly used in chemical production equipment, and is available in most product forms.

Grade 12: Grade 12 has a strength that is similar to the 300 series steels, and it has a very high formability and weldability, making it a good choice for various fabricated applications.

Grade 23: Ti 6AL-4V ELI, or Grade 23, has is often made into coils, strands, wires or flat wires. It is made of a combination of titanium, vanadium and aluminum, which gives it a very high tensile and yield strength while reducing the ductility and weldability.

Though the most common titanium alloys were listed above, there are many other, less known and used titanium alloys. Titanium alloys go all the way up to grade 38, and their characteristics and applications vary based on the alloy metals.

When determining what grade of titanium or titanium alloy that would be right for your project, consider the environment it will be in, what the part will do, and the size of the desired part.

Features of Titanium Electric Valves:

A Titanium Electric Ball Valve is an advanced industrial valve designed for precision control and durability in demanding environments. Here's an introduction to its features and applications:
