Dartt Valve Company

Dartt Valve Company manufactures the DARTT Valve, a patented downhole valve for plunger and sucker rod pumps. The valve is engineered to address gas lock, fluid pound, and pumping under packer, using design principles based on hydraulic jump theory to keep the traveling valve open through the downstroke and maintain fluid flow. The first DARTT Valve was sold in 1995, and the design has been developed through a series of patents adding features such as spin-style fins, a sand scraper, and a pump-under-packer capability. DARTT Valves are used in wells across several U.S. states and internationally, including Canada, China, Colombia, Egypt, Trinidad, and Venezuela.
