 pneumatic hard sealed Butterfly Valve flanged butterlfy valves:

Metal seat butterfly valve

Brief Introduction

Metal-sealing butterfly valves use J type flexible sealing ring and eccentric multi-level metal-sealing

structure. It is widely applied in the pipelines of metallurgy,electricity,petro-chemical,and drainage and

building to regulat flow and cut-off media.

Features

1.Metal-sealing butterfly valve uses three eccentric sealing structure, there is rarely abrasion between

seat and disc.

2.Sealing ring made of stainless steel,has the the double advantages of metal-sealing and flexible sealing. Whenever low temperature or high temperature, this valve all have good sealing effect.

3.corrosive-resistance, long service life,etc

4.disc sealing surface uses Cobalt-based carbide surfacing , the sealing surface is anti-abrasion, long life

5.big size disc uses Truss frame structure,high strength, large flow area,small flow resistance

6. two way sealing function, it is not restricted by flow direction when installment, and also not subject to spatila position, can be installed at any position.

7.driving device can be intalled multi-station (rotating 90 degree or 180 degree ), convenient for clients.
