The function of the wafer hard seal butterfly valve is mainly to regulate the flow of a fluid in the pipe, so what can affect this function?
The materials used for the valve are critical. At present, the sealing surface of the wafer hard seal butterfly valve is forged by metal materials and all the valve parts are forged by stainless steel.
In this way, the hard seal butterfly valve can well control large flow and the high flow rate of the medium in some pipes. Moreover, this butterfly valve is durable, and its service life is relatively long. Generally, this valve is made from stainless steel.

The stainless steel used for butterfly valves is wear-resistant, which can effectively improve the application of the valve in the pipe network. Currently, this valve is more suitable for cutting off or regulating the flow of a fluid in the pipe.
The wafer hard seal butterfly valve in low-temperature medium has the performance of general valves at normal temperature. What's more, this valve has reliable seals, flexible operation and some other special functions.
When the valve and the pipe adopt a flange connection, the attachment washer, the connecting bolt and the connector loosen due to their unsynchronized contraction at low temperature, leading to leakage.
When the valve is closed, the elastic seal ring first contacts with the short axis of the elliptical sealing surface, and is gradually pushed inward with the rotation of the valve stem, forcing the elastic ring to contact with the long axis of the inclined conical surface and leading to the full contact between the elastic seal ring and the elliptical sealing surface. This butterfly valve is sealed by deformation of the elastic seal ring.
Butterfly valves are widely used because they have lots of advantages such as compact structure, small size, light weight, small fluid resistance and quick opening and closing.
