Three biased multi-level metals hard seal butterfly valve series,is the long life which the our company newly develops,the energy conservation butterfly valve.
Welded ball valves are widely use in various fields, Their superior quality and high performance stability are not achieved by ordinary cast steel ball valves, The service life of all welded ball valves is far greater than that of cast steel ball valves, All welded ball valves are widely uesd in city gas, urban heating, petrochemical, shipbuilding,1
All welded ball valves are widely used in city gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment.

Valve purpose: Eccentric hemisphere valve, also known as C-type ball valve, is to make the valve unblocked or blocked by rotating the hemisphere. The switch is light and small in size. It can be made into a large diameter. It has reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often close1
Brief introduction: Because the valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function, and because the change of valve seat opening is in direct proportion to the stroke of valve disc, it is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting off or regulating an1
