Lug type Ductile iron butterfly valve for high pressure-WESDOM Group

Product Introduction

Butterfly Valve has existed for a long time and has a wide range of applications. They first appeared in the 1930s and have been used by many industries since then. Butterfly Valves are usually made of cast iron and the name comes from the functionality of the disc.

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 Table E 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.

Our general purpose Cast Iron Resilient Seat Butterfly Valves are widely used thanks to their excellent performance suitable for a wide range of applications. This product is ideal for throttling or shutting off the flow of gases, liquids, semi-liquids and even solid powder.
