D373 Wafer Type Butterfly Valve

D373 Wafer Type Butterfly Valve is a compact butterfly valve designed for pipeline flow shut-off and control. Compared with flanged butterfly valves, its wafer-type installation occupies less space and can help reduce installation costs, making it suitable for pipeline systems where equipment layout and installation efficiency are important. The wafer connection also provides a practical solution for integration between pipeline flanges.

The compact structure makes the D373 wafer butterfly valve suitable for applications with limited installation space and cost-sensitive pipeline projects. Its design is intended for reliable flow control while simplifying the installation arrangement compared with flanged valve configurations. Test and inspection can be carried out according to GB/T 13927-2022 and JB/T 9092-1999.

D373 Wafer Type Butterfly Valve is suitable for industrial water systems, process pipelines, equipment connections, and other applications requiring compact flow shut-off and control. OEM and ODM services can support customization of valve size, body materials, sealing materials, connection dimensions, pressure ratings, and operating configurations according to project requirements.
