Product Introduction

The welded metal hard seal butterfly valve adopts triple eccentric structure. This valve is designed to be an ideal hard seal butterfly valve for bubble grade seals in high temperature, high pressure, and fire protection applications. Due to the welded structure, the valve and the pipeline plane achieve permanent zero leakage. The welded butterfly valve has no flange, which brings great convenience to the insulation and bandaging of the pipeline.
