The Butterfly Valve (BFV) Solid-core Disc Design project, sponsored by Belimo Technology USA, Inc., aims to develop a cost-effective, durable, and manufacturable solid-core stainless steel disc for a 14” BFV used in commercial HVAC systems. The project addresses challenges associated with the current hollow-core disc design including debris causing leakage and a high reject rate in production by developing solid-core disc designs with a single-piece full length stem and a two-piece stem. Disc designs undergo FEA analysis, business analysis, and prototyping before component inspection, assembly, and testing is performed onsite at Belimo to evaluate performance under real-world conditions.

Our team collaborated with Mechanical Engineering 7 on this project.
