The Wafer Butterfly Valve (Half Shaft Without Pin) is specifically engineered for reliable flow control in engineering projects and water systems. Featuring a half-shaft without pin design, this valve eliminates the traditional shaft-pin connection, reducing potential leakage points and enhancing sealing performance. Its wafer-style body allows for compact installation between flanges, making it suitable for limited-space pipeline layouts.
Manufactured from high-quality materials with corrosion resistance, this wafer butterfly valve delivers smooth operation, low torque requirements, and long service life. It is ideal for medium-pressure clean water applications, municipal water distribution, HVAC systems, and other engineering projects requiring dependable shut-off and flow regulation.
As one of China’s top butterfly valve manufacturers, we offer precision-engineered wafer butterfly valves that meet international standards, ensuring performance, durability, and value for your projects.
