AD373-16C Multi level Hard Seal Butterfly Valve--Detailed Introduction

Features:

Due to the three-dimensional eccentric principle design used in this butterfly valve product, the spatial motion trajectory of the sealing surface is idealized, and there is no friction or interference between the sealing pairs. In addition, the appropriate selection of sealing materials ensures reliable sealing, corrosion resistance, high temperature resistance, and wear resistance of the butterfly valve. Its main characteristics are as follows:
1. Small opening torque, flexible and convenient, labor-saving and energy-saving;
2. The three-dimensional eccentric structure makes the butterfly valve plate tighter as it is closed, and its sealing performance is reliable, achieving no leakage;
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
