Application norm 1、Flange conjunction dimensions：GB9115.6-88、GB9115.7-88 2、Construction length ：GB12221-89 3、The pressure experiments:GB/T13927-92 Use | This butterfly valvemay be used as the startup&shutting of
pipeline system and ajustmentof liquid flux in the nuclear power
plant exhaust system, and also the airinessdust-elimination system,
environmental protection and heating airiness pipelinesystem in
power station,metallurgy, cement, construction
matericals,medicine,chemical industry etc. |
Point This valve is welded by excellent alloy steel plate, has
simplestructure,light weight,big caliber, agile&reliable
operation, thus especiallyis applicable to these occasions of low
pressure difference and big flux.
