Multi-level hard sealing butterfly valve

Model: D343H-10C / 16C

Features: Turn torque is small, flexible and convenient, energy saving

Three eccentric multi-level hard sealing butterfly valve flange Overview:

Three eccentric multi-level hard sealing butterfly valve flange series, the Department of long-life, energy-saving butterfly valve. Its three-dimensional structure using knitting heart design principle, the use of hard and soft seat seal compatible multi-level structure, process skills, and advanced technology. This product consists of the main components of the valve body, disc, multi-level seat, stem, transmission and other components. It is widely applied to the pipe metallurgy, electric power, petroleum, chemical, air, gas, flammable gas, and water supply and drainage and other corrosive media.


Since the product is used in three-dimensional eccentric butterfly design principles to make space trajectory to reach the ideal sealing surface, no mutual friction between the sealing surface, without interference, coupled with the sealing material is properly selected, allowing the butterfly valve sealing, corrosion resistance , heat resistance and wear resistance has been a reliable guarantee. Its main features are as follows:

1, open a small moment, flexible and convenient, energy saving.

2, three-dimensional knitting heart structure, the disc more closed more tight, reliable sealing performance, to no leakage.

3, high pressure, corrosion resistance, wear resistance, and long life.
