Wafer type Butterfly Valve

Wafer type Butterfly Valve

Wafer type butterfly valve is the specific and popular type among the various butterfly valves. The wafer type butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. As a result, the general applications of the wafer type butterfly valve cover a wide range of industries, especially covering the foodstuff, pharmacy and chemical industry.

Wafer type butterfly valves are able to be manufactured into a wide range of sizes so as to meet the various specifications. In terms of the working conditions, a lot of improvements have been done to suit and serve the industrial development. Wafer type butterfly valves are used for isolating or regulating flow. And the affecting part of the wafer type butterfly valve is called the disk. The on and off of the disc determines the operation of the valve.

Some types of the wafer type butterfly valves are able to bear the high working temperature, while others are not. For example the A type wafer butterfly valves are usually used for the application of the temperature less than 80 degree. Otherwise, they would fail to work, even cause some industrial accidents. Thus, it is important to realize the specifications of the chosen wafer type butterfly valve, aiming to achieve the good performance with the safe working conditions.
