Please download our the below valve drawing for reference. It is metal hard seal, three eccentric design butterfly valve, available double flange, wafer type and lug type, as well as butt welded ends. It is just for technical evaluation if you have are interested in this products. Our design allows reduced torques and excellent throttling capabilities of the offset disc assemblies. The metal-metal seal assures a perfect tightness even at pressure and/ or temperature & pressure changes.
