Worm Gear Actuator Driven Ductile Iron Wafer Type Concentric Butterfly Valve

Product introduction:

Concentric butterfly valve normally with soft seal is the preferred conventional butterfly valve for pipeline. The utility model has the advantages of simple structure, small flow resistance coefficient, near-straight flow characteristics, and is free of debris, in light weight, convenient to be installed, and small in driving torque.


Concentric butterfly valve can be operated with various type of actuators, according to user's requirements, either in manual, electric, pneumatic, or other forms, and worm gear operation is the very regular type for easy handle. Different materials are selected and seal rings of different materials are provided. The valve is applicable to different media and working conditions and makes the cost and performance to achieve the best match.


The soft seal butterfly valve is suitable for the temperature lower than 120℃ and nominal pressure lower than 1.6 MPa,and it is suitable for the industries such as water supply and drainage, sewage, food, heating, gas, shipping, hydro-power, metallurgy, energy system, and textile,particularly suitable for two-way seal box valve bodies that are easy to be rusted.
