Used in blast furnace gas pipelines for regulating and cutting off
Dual eccentric butterfly valves include wafer type and flanged type, rubber sealing or metal sealing with different operation methods.
The valve is composed of butterfly valve and piston valve
The lever cutting butterfly valve has the advantages of small structure size and light weight. The valve plate has a period of opening and closing translation process relative to the valve body at the moment of valve opening and closing, and the friction free operation can ensure the sealing performance of the sealing surface for a long time
opening moment is small, flexible and convenient, and labor-saving and energy-saving are realized.
Regulating valve has straight disc type and inclined disc type
