DrillmaxPro® 10K Drill Pipe Float Valve

Plunger Style

Model F Plunger Type ( Piston or Dart)

The Model F is a plunger type float valve that allows constant fluid flow while drilling, yet provides an instant shut-off if the flow is stopped or reversed. The piston seal stops back flow when breaking connections and keeps cuttings out of the drill string to help prevent clogged bits. In normal drilling operations the Model F offers economy and durability.


Continuous lubrication of drilling equipment, such as drill bits, minimizes friction and wear, enhancing their longevity and reducing the risk of costly breakdowns. Moreover, a steady flow of drilling fluid serves to cool and clean the drill bit, removing cuttings from the borehole and preventing clogging, which could otherwise impede progress.

Float Valve Installation

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: 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.
