Valley-Dynamo, Inc. (officially Valley-Dynamo Limited Partnership or VDLP for short) is a gaming and sporting goods manufacturing company. It has been the dominant manufacturer of coin-operated pool tables in North America for over 6 decades, and produces the US-ubiquitous Valley brand and decreasingly common Dynamo brand (once a competitor). The company also manufactures other market-leader brand names, including Tornado brand table football (foosball), Dynamo air hockey, and Champion indoor shuffleboard tables, as well as Sun Glo shuffleboard equipment, for both the home and coin-op markets.
The company has distributors in some two dozen countries. Annual sales were up to US$15–17 mil, as of May 2009, at which time Valley-Dynamo employed around 125 workers in its larger centers (approximately 60 at the Champion factory in Texas, 40 at the Valley plant in Mexico (since relocated to Texas), and 25 or so at a Grand Prairie distribution center), plus office support staff, and employees of Valley-operated leagues (see below).
