Special Material Ball Valves
Our special material ball valves include two-way, three-way, and four-way configurations available in both soft-seal and hard-seal designs with floating and trunnion-mounted options. Manufactured from high-performance materials including titanium, nickel, zirconium, Hastelloy, Monel, Inconel, duplex stainless steel, 904L, Alloy 20, and C4 steel, these valves deliver exceptional corrosion resistance, mechanical strength, and reliability across demanding industrial applications.
Floating Ball Valve Design
Floating ball valves are quarter-turn valves that utilize a floating ball mechanism for precise flow control. These valves are essential in chemical processing and other industries where reliability and control are critical:
- Material Compatibility: Constructed from materials specifically compatible with acetic acid to prevent corrosion and ensure long-term performance
- Valve Design: Floating ball design provides tight sealing for moderate to high-pressure applications, minimizing leakage risks
- Pressure and Temperature Ratings: Engineered to meet specific application requirements for safe and efficient operation
- Maintenance and Durability: Titanium construction offers exceptional durability with design features that facilitate easy maintenance and inspection

Titanium Ball Valve Features
The floating ball design allows displacement under medium pressure, creating a tight seal against the outlet end sealing surface. American Standard titanium ball valves leverage the excellent stability and self-passivation capability of titanium's oxide film to resist strong corrosion in harsh working conditions.
- Low Flow Resistance: Minimal fluid resistance even in reduced bore configurations
- Excellent Sealing Performance: PTFE sealing rings ensure reliable sealing with increasing medium pressure
- Reliable Stem Sealing: 90° rotation operation protects packing seals with reverse seal pressure enhancement
