[18] BUTTERFLY VALVES

Butterfly Valves

Resilient 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.

1. Wafer Butterfly Style

The body design is such that it can be used with most international flanges including AS2129, BS10, ANSI, DIN & JIS Standards in sizes 50mm to 300mm. The wafer style is designed for inline service and relies on a flange either side of the valve to secure in the pipeline. *AAP 50mm to 300mm Wafer Butterfly Style EPDM version is Australian Standard Watermark (Certificate No: WMKA25460) approved and using Akzo Nobel Paint

2. Lugged Butterfly Style

Like the wafer style, the lugged body is compact but has a series of lugs cast into the body which are tapped with a metric 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. *AAP 50mm to 300mm Lugged Butterfly Style EPDM version is Australian Standard Watermark (Certificate No: WMKA25460) approved and using Akzo Nobel Paint
