120" Diameter Butterfly Valve Body for the National Water & Sewer Industry
Davis Machine & Fabricating was contacted by a national water and sewer industry customer to construct a 120" diameter butterfly valve body to accurate dimensions. This challenging project required manufacturing systems able to process such a physically large and heavy design. Our facilities were flexible enough to overcome the challenges posed by this project.
Our primary applied procedures were CNC machining and boring. We used a 14’ Vertical CNC Boring Mill along with a 5-axis Horizontal Boring Mill with rotary table, capable of producing the 8,000 lb. design. Our material was ductile iron, machined within dimensional tolerances of ±0.002." We also applied a 2-part epoxy coating and finished open surfaces to 63 – 125 RMS.
Quality control checks, including dimensional inspection and visual inspection were employed during and at the end of the production process. Volumes of 1 to 5 units per order were each delivered to various locations on 3 to 5 week lead times.
This customer received a comprehensive fabrication solution that did not shy away from challenging design requirements. Davis Machine & Fabricating remains committed to bringing successful production to demanding projects without sacrificing quality or accuracy.
