Hard Seal Wafer Butterfly Valve

Classification：

Summary

Because the butterfly valve of this product is designed on the principle of three-dimensional eccentricity, the spatial trajectory of the sealing surface can be idealized, and there is no friction and interference between the sealing surfaces. In addition, the sealing material is properly selected, so that the sealing performance and corrosion resistance of the butterfly valve can be improved.

PRODUCT DETAILS

Product Description

1. The opening torque is small, flexible and convenient, labor-saving and energy-saving;

2. The three-dimensional braided core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable to achieve no leakage:

3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
