Industrial Wafer Type Butterfly Valves are butterfly valves that are used for the transfer of liquids and gases between two vessels. They are commonly used in industries where there is a need for precise control of flow rates. They are also used in chemical and pharmaceutical manufacturing plants, where precise flow rates are required.
They are made from a variety of materials. They are designed to be durable and to last for a long period of time. They are also easy to install and to operate, which makes them an ideal choice for industrial applications.
