Adopt to the special hole and stem in the disc and stem, realize the non-pin connection
which make the disc floating and reduce friction force between the body and the seat.
Thus reduce the torque greatly. The disc floating realizes manufacture craft and use of single
eccentric butterfly valve. The user may choose different seal according to operating condition, achieves the different seal effect.
Safety and trustiness, anti- corrosion completely are the distinct characteristics of our products.
This changeable eccentric butterfly valve can reach zero leakage.
Compares with other eccentric butterfly valve, this structure of valve has following
Advantage: lower requests to the components processing precision, high interchange ability, low cost.
