Product Description
The SS316 Disc PTFE Seat Wafer Butterfly Valve with Handle is intended for on-off isolation in low to medium pressure pipeline systems. The SS316 stainless steel disc is selected for its resistance to corrosion and chemical attack, while the PTFE seat provides consistent sealing performance where elastomer seats may be unsuitable.
This wafer-type butterfly valve is manually operated by a handle and is typically applied in smaller diameters where frequent operation and compact installation are required. It is commonly used in clean water, chemical process lines, and industrial service where reliable shut-off is more critical than flow regulation.
