Product structure and performance introduction

Product structure

Characteristics

Multi-level hard seal butterfly valve series products, the company's newly developed long service life,

energy-saving butterfly valve, the structure adopts the three-dimensional eccentric principle design, the valve

seat is compatible with the hard and soft sealing of the multi-level structure, superb processing, advanced

technology. This product is composed of valve body, butterfly plate, multi-layer valve seat, valve stem,

transmission mechanism and other major components.

As this product butterfly valve adopts three-dimensional eccentric principle design, the spatial movement

trajectory of the sealing surface is idealized, and the sealing surfaces have no friction and interference with

each other, coupled with the proper selection of sealing materials, thus the sealing, corrosion resistance,

temperature resistance and abrasion resistance of the butterfly valve are reliably guaranteed. Its main

characteristics are as follows;
