Water type butterfly valves are specially designed for fluid control needs in water systems. With their efficient and practical characteristics, they have become key equipment in water supply and drainage engineering and related fields.

In terms of structural design, the water type butterfly valve adopts a classic combination of butterfly plate and valve stem. The butterfly plate can rotate 90 degrees around the axis of the valve stem to achieve rapid opening and closing. Valve bodies are often made of corrosion-resistant materials such as ductile iron and stainless steel, with smooth inner walls that can effectively reduce water flow resistance. The sealing surface is usually equipped with water-resistant sealing materials such as EPDM and NBR to form a tight fit, ensuring that the valve can achieve reliable sealing under different water pressures and prevent leakage and dripping.

In terms of performance, water type butterfly valves have excellent operational flexibility. Its opening and closing process has a small torque, making it easy to control whether it is a manually operated small valve or a large valve with electric or pneumatic actuators, making it convenient for workers to accurately adjust water flow according to actual needs. In addition, the valve has good anti erosion performance and can maintain stable operation even under frequent changes in water flow, with a long service life.

In terms of application scenarios, water type butterfly valves are widely used in urban water supply systems to ensure the stability and safety of tap water transportation. In sewage treatment plants, it can be used to regulate the flow of sewage and sludge, helping the sewage treatment process to proceed smoothly. In water conservancy projects, such as reservoir discharge and river drainage, butterfly valves also play a key control role.

With reliable sealing performance, convenient operation, and wide applicability, water type butterfly valves have become the core equipment for fluid control in the water industry, providing solid guarantees for the rational utilization and efficient management of water resources.
