Product Overview

The UPVC pneumatic butterfly valve is a type of butterfly valve made mainly of unplasticized polyvinyl chloride (UPVC), combined with an air-driven actuator for operation. It has a simple structure, is lightweight, and has strong corrosion resistance. It is widely used in fluid control systems in industries such as chemical engineering, water treatment, environmental protection, food, and pharmaceuticals, especially for regulating and cutting off corrosive media or high-purity fluids.
