Wafer butterfly valve

Wafer butterfly valve

A wafer butterfly valve refers to the valve with a valve body having a through opening. The opening forms a fluid flow passage and has a wall coaxially surrounding. The common manufacturing materials such as the cast iron and stainless steel are used to manufacture the wafer butterfly valves. Despite of the body, shaft, disc, bushing and ring, the heavy duty epoxy coating is applied to improve the durability.

Resulting from the difference on the designs and manufacturing materials, various wafer butterfly valves hold the different suitable pressure ratings and performance. As a result, the wafer butterfly valves are popular during the whole industrial process. For example, they are usually easy and trouble free mounting in the pipeline, as well as the little maintenance. And the primary and secondary seals integrate with body lining in order to ensure compatibility with media. And the long service life, easy operation and tight shut-off are all appreciated. What else, the wafer butterfly valves are suitable for the control of steam, water, hot gases, powders, slurries and aqueous slurries of an abrasive nature under the corresponding permitted temperature and pressure.
