一．Product Introduction
The V Notch Ball Valve is a specialized control valve engineered for accurate flow regulation and efficient on-off operations in industrial piping systems. Characterized by a V-shaped notch in its ball component, this valve is adept at handling a wide spectrum of media, including liquids, gases, and even abrasive slurries. It finds extensive application in industries such as petrochemicals, water treatment, power generation, and fine chemicals, where precise flow control and robust performance under demanding conditions are paramount.
Constructed to deliver consistent performance, the V Notch Ball Valve combines the advantages of ball valves and control valves. Its unique V-notch design enables it to achieve linear or equal percentage flow characteristics, making it a reliable choice for processes that require meticulous flow modulation. Whether it’s regulating the flow of corrosive chemicals or managing the pressure in power plant pipelines, this valve stands out for its versatility and durability.
二．Product Features
