Key features and benefits of the 80WM580 Wafer Pattern Butterfly Valves.

Key Features

Bronze butterfly valves are an excellent solution if you require a valve that will function properly even when exposed to corrosive media such as seawater or brackish water. These bronze valves offer maximum protection against erosion from aggressive liquids like saltwater.

Key Features

The TTV range of bronze butterfly valves is the perfect solution for most marine applications and comes with approvals from recognised bodies such as DNV, Bureau Veritas Lloyds & ABS. Our products are corrosion resistant and suitable for sea water environments.

Key Features

The quarter turn action offers quick opening or closing with ease of operation and the valve has good flow control characteristics. In the wide open position, the only obstruction to flow is that due to the thickness of the disk, so the pressure drop across the valve is small.
