FO1-BV1LT-1L(Lugged type Butterfly Valve–Handle Operation)
●Brief
Adaptable LUG butterfly valve range for all types of fluids and constraints
Assembled above ground to resolve congestion problems, the LUG range of ductile iron butterfly valves is installed using bilateral screws (and no nuts). It can be adapted for all types of fluid and constraint and, like WAFER, LUG butterfly valves have two friction points.
●Features
1.Lug butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power station.
2.It is used for gas pipeline in sulfuric acid industry: inlet and outlet of blower in front of furnace, inlet and outlet of relay fan, series connection valve of electric mist eliminator, inlet and outlet of S02 main blower, converter regulation, inlet and outlet of preheater, etc.
APPLICATION
General Use: Water,sea water,gas, pressurized air, acids etc.
