Centerline Butterfly Valves
Oct 03, 2018

The structural features of the midline butterfly valve are the center of the stem, the center of the butterfly plate and the center of the valve body in the same position. The structure is simple and the manufacture is convenient. Because butterfly plate and valve seat are always in extrusion, scratch state, large resistance distance, wear fast. In order to overcome the extrusion, scraping, to ensure sealing performance, the valve seat is basically made of elastic materials such as rubber or PTFE, but also due to the use of sealing materials in the temperature limit.
