MTVB/MTVBA/MTVBB/MTVBC Floating Ball Valves floating ball valves are designed for tight shut-off, durability, and safe operation in demanding industrial environments. With a service range from –50°C to 200°C (–58°F to 392°F), sizes from ½ inch to 12 inch (15–300 mm), and a pressure range up to ASME Class 150 – Class 2500 (2.0 MPa – 25.0 MPa), these valves deliver versatile performance across water, power, chemical, and oil & gas industries.
All models comply with NACE MR0175 for sour service and are equipped with fire-safe and emission-control features.
