Product Description

The Aluminum Bronze Disc PTFE Seat Wafer Butterfly Valve with Handle is intended for manual isolation service in pipelines handling corrosive or chemically aggressive media. The aluminum bronze disc is selected to improve resistance to seawater and corrosion compared with standard ductile iron or carbon steel materials, while the PTFE seat provides reliable sealing where rubber seats may be unsuitable.

This wafer-type butterfly valve is operated by a manual handle and is typically applied in smaller and medium pipe sizes where frequent operation and simple control are required. The Aluminum Bronze Disc PTFE Seat Wafer Butterfly Valve with Handle is commonly used in marine systems, chemical process lines, cooling water circuits, and industrial water treatment applications that require dependable shut-off rather than precise flow control.
