Two-Way Ball Valve ASME DN 15 Gr2 Gr5 Titanium Industrial Ball Valve
The Two-Way Ball Valve ASME DN 15 made from Gr2 and Gr5 Titanium is a high-performance valve solution for industrial applications. It combines the superior corrosion resistance, strength, and durability of Titanium Gr2 and Gr5 to ensure reliable performance in challenging environments, including chemical processing, oil & gas, and marine industries.

Overview of Gr2 and Gr5 Titanium
- Gr2 Titanium: A commercially pure titanium alloy known for excellent corrosion resistance, particularly in environments exposed to seawater, acids, and chemicals. It offers great fatigue strength and durability in moderate-to-high temperature ranges.
- Gr5 Titanium (Ti-6Al-4V): An alloy of titanium with 6% aluminum and 4% vanadium, offering superior strength, excellent fatigue resistance, and high-temperature performance. It’s typically used in aerospace and high-stress industrial applications due to its exceptional strength-to-weight ratio.
Key Features:
- Material Options: Available in Gr2 (pure titanium) and Gr5 (titanium alloy), catering to various application needs based on strength and corrosion resistance.
- Two-Way Operation: The valve operates in a bi-directional flow system, making it versatile for different fluid control applications.
- Compact Design: With DN 15 (½ inch) size, it is perfect for space-constrained installations while maintaining full performance.
- Corrosion Resistance: Both Gr2 and Gr5 offer exceptional resistance to aggressive chemicals, saltwater, and harsh environments.
- Temperature and Pressure Resistance: The valve performs effectively in a wide temperature range and is designed to withstand high-pressure environments.
