Extended stem butterfly valves are a uniquely designed and widely used valve product. Its characteristic is that the length of the valve stem is increased compared to ordinary butterfly valves, so that the valve can withstand greater pressure. The following are the main application areas and characteristics of extended stem butterfly valves:

Application areas

Petrochemical industry: Extended stem butterfly valves are often used to control various chemical fluid media, such as gas, oil, acid and alkali liquids, etc. Its structure is simple and the switch is fast, which is suitable for the pipeline system in petrochemical plants.

Sewage treatment industry: In sewage treatment projects, extended stem butterfly valves are widely used in water supply pipes and drainage pipes to control the flow and pressure of sewage. Its economic, practical and easy maintenance characteristics make the sewage treatment process more efficient.

Other industries: In addition, extended stem butterfly valves are also widely used in papermaking, mining, electricity, liquefied gas, municipal administration, mechanical equipment supporting, electronic industry and other fields to adjust the flow and cut off the medium.
