Description

A wafer-type butterfly valve featuring an aluminium bronze disc and PTFE seat, intended for manual isolation service in pipelines handling corrosive or chemically aggressive media. The aluminium bronze disc provides improved resistance to seawater and corrosion compared with standard ductile iron or carbon steel disc materials. Operated by a manual handle and suited to smaller and medium pipe sizes requiring frequent operation and dependable shut-off.
