Category : Electric ball valve
Product Name: Stainless Steel Flange Electric Ball Valve
Product introduction:

Stainless steel flange electric ball valve is a rotating ball valve with the angle range from 0 degree to 90 degree which presents good seal performance large flow capacity small flow resistance coefficient simple structure convenient maintenance long service life. The channel of the body and the connecting pipe has the equal diameter to be connected together which allows medium to flow almost no loss.
The EK series valves are usually used in the occasion of high sealing performance requirements to control not only the medium of gas liquid but also the medium of sewage and fibrous impurity medium which is widely applied in the fields of petroleum chemical metallurgy light industry papermaking power station refrigeration and so on.
