ASME Gr5 Gr7 Two-Way Ball Valve Titanium Industrial Ball Valve High
Pressure Release Valve
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.

Applications
- Oil & Gas Industry: Used in high-pressure pipelines, refineries, and offshore
platforms where pressure release and corrosion resistance are
crucial.
- Chemical Processing: Perfect for controlling fluid flows and managing high-pressure
systems in chemical manufacturing, particularly in the presence of
aggressive chemicals.
- Petrochemical Industry: In environments where valves must handle extreme pressures and
ensure safe release, particularly for chemicals that may be
corrosive or hazardous.
- Marine Applications: Gr7 titanium’s resistance to chloride-induced corrosion makes it
ideal for marine applications, including offshore installations and
shipbuilding.
- Aerospace: Given the high strength and lightweight nature of Gr5, this valve
is also used in aerospace applications where pressure release and
minimal weight are essential.
