Welded Butterfly Ball Valve

Main Performance Parameters

Application
This valve series features automatically or manually operated butterfly ball valves designed to handle viscous or particulate media. Widely used for flow regulation and control in water, food, herbal extracts, beverage, protein, and biopharmaceutical fermentation pipeline systems.

Material
• Body Material: CF8 (304)/CF3 (304L)/CF8M (316)/CF3M (316L)
• Seals: Silicone rubber (VMQ)/Fluorocarbon rubber (FPM)/EPDM/PTFE

Standard Design
Butterfly ball valves adopt forged stainless steel manufacturing process with high rigidity and compact size, suitable for piping systems requiring short face-to-face dimensions. Available in DIN/3A/SMS/ISO/BS/RJT standards. Features welded/quick-connect/external thread connections for various piping interfaces, particularly applied in water, food, herbal extracts, beverage, and bioprocessing systems. Compatible with multiple actuators for automated control.
