BUTTERFLY VALVE

Butterfly valve is on/off by the turning of the stem which operate the round butterfly disc.It is mainly used as cut-off valve and also can be designed as regulating or cut-off /regulating combined valve.currently,butterfly is mainly used in the low pressure largesize pipelines.

butterfly valve panels installed at the Tip of the diameter pipeline direction.In butterflyvalve body flight corridors,the disc-shaped Tip boards around rotary axis,rotation anglefor 0°-90 meridian east between rotary to+90,the valves are open all licence conditions.

butterfly valve structure simple,small size,light weight,only by a few parts.But itcan be rapidly open and close-90E,simple to operate,while the fluid control valves havegood character,butterfly valve a fully open position,Tip board thickness is only whenthe medium flows through body resistance,the pressure generated by the air valves small,it has a better flow control characteristics,butterfly valve a metal shells sealed andthe two sealed sealed patterns.Flexible sealed valves,seal ring can embed in body orperipheral boards to Tip.
