Sealing theory of three-eccentric butterfly valve:Production Catagory:
|The three-eccentric metal seal butterfly valve is energy saving valve and has long service life.|
|It is designed as per three-dimensional eccentric theory.The seat is adopted of multi-layer structure mixed hard seal with soft seal together or full metal seal which can be used in higher temperature and pressure working conditions.This products is widely used in metallurgy,iron&steel,power,petroleum,chemical,heat supply,air,coal gas,flammable gas,city water supply&drainage to cut off and regulate medium flow|
|The three-eccentric butterfly valve as the latest science&technology achievement has all of the advantage and avoids all of the shortage of the other valves.And more over,about this kind of valves,there are many kinds of materials for selection,so they are able to be used in any kind of acid and alkali working conditions.Especially for the large size three-eccentric butterfly valve,because of the advantage of zero leakage,it replaces other heavy and expensive on-off valves slowly and slowly.|
