The ASME Gr5 Gr7 Two-Way Ball Valve made from Gr5 (Ti-6Al-4V) and Gr7 (Ti-0.3Mo-0.8Ni) titanium alloys is specifically designed for high-pressure release applications. This valve combines the strength and durability of Gr5 titanium, with the added corrosion resistance and high-temperature capabilities of Gr7 titanium, making it an ideal solution for industries that require robust performance under extreme conditions such as high pressure and harsh environments.
Overview of Gr5 and Gr7 Titanium
Gr5 Titanium (Ti-6Al-4V): Known for its outstanding strength-to-weight ratio and excellent fatigue resistance, Gr5 titanium is a titanium alloy that is used widely in aerospace, automotive, and industrial applications that demand high strength and durability.
Gr7 Titanium (Ti-0.3Mo-0.8Ni): Gr7 titanium is an alloy of titanium that includes small amounts of Molybdenum (Mo) and Nickel (Ni), enhancing its corrosion resistance, especially in environments exposed to chloride-induced stress corrosion cracking. It is ideal for applications where both high corrosion resistance and strength are critical.
Key Features:
High Pressure Release Valve: Specifically designed to handle high-pressure situations and release pressure safely and effectively, making it ideal for industries like oil and gas, petrochemical, and chemical manufacturing.
Gr5 and Gr7 Titanium Alloys: Combines the superior strength of Gr5 with the corrosion resistance of Gr7, making it suitable for demanding applications in both moderate and harsh environments.
Two-Way Flow Control: Offers reliable bi-directional flow control for efficient fluid management in critical applications.
Temperature Resistance: The materials used in this valve offer excellent high-temperature performance, withstanding temperatures up to 450°C.
Compact and Durable Design: Designed for industrial environments that require compact, yet durable, high-performance valve solutions.
