Drillmax® Model GA
Full Flow Flapper Type with Carbide Insert Port
The Model GA is identical to the Model G except for a small hole in the middle of the flapper that makes the flapper ported. This port facilitates the ability for differential pressure readings at the surface. The port also allows for partial automatic filling of the drill pipe, during run in.
