Ball valve sealing surface is spherical; The sealing surface of the butterfly valve is an annular cylinder;The sealing surface of the gate valve is flat
Electric fixed ball valve according to the different installation of the seat sealing ring which suitable for long distance pipeline and general industrial pipeline;Floating ball valve can rotate freely in the seat ring with the help of the stem.
Overload and ambient temperature is too high will influence electric valve run. So provide good working environment, control voltage environment can bring good use of electric actuator valves.
New parts also need to be cleaned before assembly.Metallic parts that have not been decomposed can be scrubbed with clean;After cleaning, it is necessary to be assembled after the volatilization of cleaning agent on the washed wall surface
Butterfly valve is suitable for flow regulation.Because the butterfly valve in the pipeline pressure loss is relatively large.Butterfly valve structure length and overall height is small, fast switching speed, good fluid control characteristics.
