The DAV MX™ is a multi-function, multi-cycling circulating sub which is activated with our patented MX™ Smart Dart technology. The system raises the bar on performance and reliability without adding complexity for the user. With several patented features, such as hold open and latch & seal, the tool is clearly the smart choice for CircSub users.

Features & Benefits


Our range of Smart Darts provides users with split flow, full-bypass and well control options for a countless number of applications


Unlike with conventional balls, DAV MX™ darts will not blow-thru on opening therefore can be pumped down at much higher speeds


The tool is simple and easy to operate, requiring no service hand


The DAV MX™ cycling is largely immune to variations in angle, temperature, pressure, mud type and weight, meaning it can be run in virtually any environment and for endless applications
