Product Specification

ANSI B16.34 Titanium Gr2/Gr7 PN16 Flange Ball Valve for Chemical and Power Industry (DN10-DN200)

The ANSI B16.34 Titanium Gr2/Gr7 PN16 Flange Ball Valve is a high-performance valve commonly used in the chemical and power industries. Manufactured using Grade 2 (Gr2) and Grade 7 (Gr7) titanium alloys, this valve offers superior durability, corrosion resistance, and mechanical strength, which are crucial in demanding industrial environments. This valve is designed to handle a wide range of applications from DN10 to DN200 sizes and pressure ratings up to PN16. Below is a detailed description and breakdown of the key features and advantages.

Key Features:

1. Material Selection (Titanium Gr2/Gr7):

   • Gr2 Titanium: Known for its excellent corrosion resistance, especially in chemical environments. It is highly resistant to acids, chlorides, and seawater, making it ideal for industries dealing with aggressive chemical fluids.
   • Gr7 Titanium: An alloy that adds palladium to Gr2, enhancing its resistance to reducing acids such as sulfuric acid. Gr7 offers improved strength and is particularly suited for high-performance chemical applications where corrosion resistance is critical.

2. Flange Design (PN16):

   • PN16 Flange: This valve features a PN16 flange, which ensures the valve can handle moderate to high pressure up to 16 bar. The flange design is compatible with international pipe systems, ensuring easy integration into existing installations.
   • The valve’s flanged design ensures tight and secure connections, minimizing the risk of leaks in high-pressure systems.

3. Ball Valve Construction:

   • Full Port Flow: The ball valve design allows for full-port flow, meaning there is minimal resistance to the fluid flow when the valve is fully open. This is especially important in applications requiring high flow rates and minimal pressure drop.
   • Quick Acting: Titanium ball valves offer smooth operation, allowing for quick on/off control, which is essential in critical chemical processing or power generation systems.
   • Leakproof Design: These valves are designed to prevent leakage through the sealing surfaces, ensuring reliability in systems with high demands on fluid containment.

4. Pressure Rating (PN16):

   • With a pressure rating of PN16, this valve is suitable for industrial applications where pressure ranges up to 16 bar are common. This makes it ideal for the chemical and power industries, where the ability to withstand moderate pressures while maintaining excellent sealing performance is necessary.

5. Size Range (DN10-DN200):

   • The valve is available in sizes from DN10 to DN200, accommodating a wide range of flow requirements. Larger sizes allow for handling higher volumes of fluid, which is crucial in large-scale industrial systems.

Applications in the Chemical Industry:

• Acid & Alkaline Handling: Titanium Gr2 is particularly resistant to aggressive chemicals such as hydrochloric acid, sulfuric acid, and other strong alkalis. The Titanium Gr7 adds additional protection against reducing acids, making this valve ideal for use in chemical reactors, mixers, and transport pipelines where aggressive fluids are common.
• Corrosive Gas Transport: The valve’s resistance to corrosion extends to gas handling as well, making it suitable for systems that transport corrosive gases or vapors, such as chlorine or hydrogen sulfide.
• Pharmaceutical Manufacturing: Due to its high purity, titanium is used in the pharmaceutical industry for handling sensitive ingredients, ensuring contamination-free flow.

Applications in the Power Industry:

• Steam and Water Handling: In power plants, this valve can be used in high-temperature systems where steam and water must be transported at high pressures, requiring a valve that can withstand both temperature extremes and mechanical stress.
• Nuclear Power: Titanium’s resistance to corrosion in high-radiation environments makes this valve suitable for the nuclear power industry, particularly for use in cooling systems and water treatment processes.
• Energy and Utilities: Used in various energy and utility systems that involve the transport of fluids in high-pressure and high-temperature conditions.

Advantages of Titanium Gr2/Gr7 Ball Valve:

1. Corrosion Resistance: The titanium alloy provides outstanding resistance to aggressive chemicals and acids, making it ideal for use in chemically harsh environments.
2. Strength-to-Weight Ratio: Titanium alloys, particularly Gr7, provide high strength while remaining relatively lightweight compared to other metals, making handling and installation easier.
3. Longevity and Durability: Titanium valves are known for their long service life. Their resistance to corrosion and wear reduces the need for frequent maintenance and replacements.
4. Temperature Resistance: Titanium Gr2 and Gr7 can function effectively in high-temperature environments (up to 400°C), ensuring reliable performance in power plants and chemical reactors.
5. Safe and Leak-Free Operation: The precise design and tight sealing capabilities of the valve ensure leak-free performance, even under high pressure, which is crucial for safety in chemical and power systems.
