Valley is the exclusive sales and support provider in California for Doosan Infracore America, a subsidiary of Doosan Infracore, the largest heavy-duty engine manufacturer in Korea and among the largest manufacturers in the world. Doosan Infracore America is headquartered near Atlanta, Georgia, where it has developed a multi-million dollar technical and sales training center and houses an extensive inventory of over 68,000 parts in their Parts Distribution Center.

The Doosan GK11 CNG engine is the engine of choice for transit and refuse customers. It is certified by CARB and the EPA to run on clean compressed natural gas, making it cleaner burning and more fuel-efficient than its competition.


With the engineering expertise of Valley and Doosan, several Southern California transit agencies are currently running their fleets on the GK11 CNG model engine.


The back and front end of the GK11 were designed to accommodate US transit bus applications. Better fuel economy, more power, easier serviceability, lower noise levels, all while meeting more stringent emission levels drives the GK11 to the top of its class.
