Valve Description:  butterfly valve


Butterfly Exhaust Valve - Large Diameter Gas Butterfly Valve


Valve Application:  butterfly valve


Motorized steel butterfly valve is for hydro, gas, electric power, metallurgy, chemical industry, municipal and other industries (clean water or sewage) gas, natural gas, air and other flammable gas industrial pipe, used to cut off or regulating media flow.

Valve Features: butterfly valve


1, Three-dimensional triple offset design;
     Eliminate contact friction between the seal and seat during opening process, so as to extend valve life;   

     Friction free stroking: The geometric design of sealing components provides friction-free stroking throughout the valve – extends valve life, ensures no over-travel of the disc and allows for a lower torque-range actuator to be fitted. 
     Ensure minimum pressure angle is greater than the friction angle between disc and the seat to eliminate rail clamp and stuck phenomenon;
2, Stainless steel non-metallic composite material, good sealing effect, convenience for replacing;
3, The discrete and horizontal two structures;
4, The working pressure refer to GB9131 pressure - temperature difference  level selection.


5, Metal to metal sealing: Allowing for higher pressure and temperature applications whilst still providing bubble-tight shut off.
