A wafer type butterfly valve with pneumatic operation is a compact and efficient valve used for regulating the flow of fluids in pipelines. The wafer-type design allows for easy installation between flanges, offering a cost-effective and space-saving solution. The valve features a rotating disc that controls the flow, and the pneumatic actuator enables automated operation, providing quick and precise control of fluid flow without the need for manual intervention. This type of valve is ideal for applications requiring frequent or remote operation, such as in automated systems or where high-speed control is needed. Commonly used in industries like water treatment, chemical processing, and HVAC, it is valued for its durability, ease of maintenance, and reliability in controlling flow in various fluid handling systems.
