The Integral High-Temperature Ball Valve is a specialized ball valve designed for high-temperature services. Its integral body construction reduces potential leak paths, enhancing the valve's overall rigidity and reliability. By utilizing special high-temperature resistant materials for its seats (such as PPL, hard alloys) and incorporating design features like extended stems and heat sinks to protect the packing and actuator, it can operate stably and continuously in environments up to 400°C or higher. This valve is widely used in steam systems, thermal oil pipelines, and the petrochemical industry as a reliable shut-off and control device for high-temperature media.
