Drillmax - Model FA -Ported Plunger Type Float Valve
The Model FA offers all the standard features of the Model F with the added benefit of a ported plunger, a special port which allows fluid a path through the center of the valve. This feature allows for an automatic partial filling of the drill pipe during run in, and facilitates differential pressure reading at the surface.
Drillmax Drill Pipe Float Valves are easy to install. Simply lubricate the side seal rubbers and slide the float valve into the float bore of any tool that’s been prepared for a float valve.
CAUTION: Unless you are using automatic fill Models GC and Model GCA, fill the drill pipe regularly when going in the hole. Failure to do so can cause damage to the drill pipe, well formation and/or the float valves. Double stacking is not recommended unless using a Model GS Float Valve.
