Year Founded:


From our humble beginnings as a small smithery in 1859, MWH has been committed to finding new and better ways to serve our customers. Nearly a century of expertise in forging led to our move in 1948 to produce valves for heavy diesel engine builders. Over the years, MWH evolved to develop, manufacture and service key components for all types of 2-stroke and 4-stroke engines. We further expanded to include manufacturing and reconditioning of cylinder heads, cages, exhaust-valve assemblies, valves, seats, guides and rotators - more than 10,000 products in all.

Today, we are a worldwide leader in 'cylinder head systems' and house the new MWH Innovation Center and Engine Lab focused on improving engine efficiency, reliability, emissions performance and cost of ownership. You can be confident that engines produced with MWH systems will always lead the market in cost-effective performance.
