Wafer Butterfly Valve – China Manufacturer & Supplier

Premium Quality Wafer Butterfly Valves from China

As a professional China wafer butterfly valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance wafer butterfly valves for a wide range of industrial applications. Our wafer butterfly valves are engineered to provide reliable flow control and shut-off performance in water treatment, oil and gas, chemical processing, power generation, and HVAC systems.

Wafer butterfly valves operate by rotating a built-in disc by 90 degrees to start, stop, or regulate flow. This simple yet effective design offers significant advantages over traditional gate and ball valves: wafer butterfly valves are lightweight, compact, corrosion-resistant, and offer quick operation. Unlike lug-style butterfly valves which have threaded lugs around the valve body, wafer-style valves rely on the bolts of the pipeline flanges for fixation, saving space and reducing weight. In fact, a wafer butterfly valve is lighter and costs 20-40% less than its lug-type equivalent. The wafer-style design allows for easy installation between flanges without requiring additional bolt holes, reducing space and weight while maintaining a tight shut-off and low-pressure drop.

Manufactured in strict accordance with API 609, EN 593, AWWA C504, and ISO 5752 standards, our wafer butterfly valves are available in a wide range of configurations. Size ranges cover DN50 to DN2000 (NPS 2″ to 80″), with pressure ratings up to PN25 and temperature ranges from -46°C to +450°C depending on seat material selection.
