The American Standard Hard Sealed C-Type Ball Valve from CTV offers a reliable and durable solution for critical flow control in a wide range of industrial systems. With a size range from DN50 to DN1600 (NPS2 to NPS64) and a pressure class from 0.6MPa to 25.0MPa (Class150 to Class1500), this valve is engineered to handle complex working conditions with ease.

This hard sealed C-type ball valve is widely applied in industries such as petrochemicals, power generation, metallurgy, natural gas, municipal pipelines, and water treatment. Its metal-to-metal sealing structure delivers superior shut-off performance and ensures zero leakage, even under high-pressure and high-temperature conditions.

The valve’s hard sealing surfaces—typically treated with tungsten carbide, chromium carbide, or Stellite alloy coatings—exhibit exceptional wear resistance, corrosion resistance, and thermal stability. These features make the valve suitable for abrasive media, high-viscosity fluids, and corrosive environments, where soft-seal valves may fail to perform.

Built with high-quality materials such as carbon steel, stainless steel (304, 316), and various alloy steels, the valve body and internals can be tailored to meet customer-specific requirements. For corrosive or sour service environments, material options comply with NACE MR0175/MR0103 standards, ensuring long-term safety and reliability.

The C-type ball valve is designed with a quarter-turn operation, offering simple and efficient open/close control. It supports manual, pneumatic, electric, and hydraulic actuators, and can be integrated into automated process control systems for precise flow regulation. With low operating torque and minimal maintenance, it reduces downtime and operational costs.

This valve complies with multiple international standards, including ASME B16.34, API 6D, ISO 5211, and ANSI standards. Key safety features such as anti-blowout stems, anti-static devices, and fire-safe designs are also available, meeting the strictest application requirements in critical sectors.

Thanks to its robust construction, long sealing life, and adaptability to extreme environments, the hard sealed C-type ball valve is a preferred choice for engineers and plant operators aiming for maximum safety, performance, and reliability. Whether managing superheated steam, slurry, or highly corrosive chemicals, this valve delivers consistent results.

CTV remains committed to technical excellence and engineering innovation, offering tailored valve solutions for complex and high-demand systems. With a strong focus on quality and performance, CTV continues to serve global industries with dependable flow control products.
