BUTTERFLY VALVES

A-Disc Butterfly ValvesResilient seat Butterfly Valves are used in a wide range of Industries including HVAC, Gas, Petrochemical, Pulp & Paper, Water & Wastewater Treatment, Brewing, Food processing, Mining, Textile and General Industry. They are compact and give bubble tight shut off as well as having good regulating capabilities.

Wafer Butterfly StyleThe body design is such that it can be used with most international flanges including AS2129, BS10, ANSI, & DIN Standards. The wafer style is designed for inline service and relies on a flange either side of the valve to secure it in the pipeline.

Lugged Butterfly StyleLike the wafer style, the lugged body is compact but has a series of lugs cast into the body which are tapped with a thread for the fixing of a flange on one side at a time. The benefit of this being the valve can be mounted at the end of a pipeline without the need for a flange on the downstream (discharge) side of the valve. ie dead end service.

Gear Operators (Optional)For precise regulation where flow control is critical, or on larger diameters & higher pressures.

Other Seat materials available on request. Refer to Asmuss for operating torque details.
