What is 3 Inch Wafer Type Butterfly Valve?

Butterfly valve 3 inchis a flow control mechanism that uses a rotary disk to control the flow medium in the system. The disk remains in the passage, but since it is so thin, it gives very little resistance to the flow.

The most common type of butterfly valve arrangement is a centric or a concentric butterfly valve. This type of butterfly valve consists of the stem which travels along the middle line of the disk in the center of the pipe bore and the seat is inside diameter of the body of the valve. This no offset valve configuration is also known as a resilient-seated valve as it depends on the flexibility of the seat rubber when the flow is closed, for the reliability of the seal. In this type of valve, the disk first interacts with the seat at about 85° for a 90° rotation. Concentric butterfly valves are widely used in low-pressure applications.
