THE DON MASHBURN, INC. DROP IN CHECK VALVE is an essential drilling tool that prevents return flow during a kick. It can be used in most drilling situations where return flow through the drill string is a risk and the benefits of a full bore sub are needed during normal operation. The drop in check valve can be pumped into place when needed and removed when fluid operations can resume.
