DrillmaxPro® 10K Drill Pipe Float Valve
Flapper Style
Model G Flapper Type Float Valve
Full Flow Flapper Type
The Model G is a flapper type float valve that offers unobstructed flow through the float valve. It’s designed for abrasive drilling fluids. The flapper closes to prevent cuttings from entering the drill string when flow stops and acts to assist BOP equipment in maintaining control over pressure in the drill string. The Model G features an investment cast flapper that is quick opening, allowing full flow through the valve. It fully opens when joints are raised from the hole, preventing drilling mud from being released onto the rig floor.
Model GC Flapper Type Float Valve
Full Flow Flapper Type Automatic Fill
The Model GC is identical to the Model G but adds an automatic fill feature when going in the hole. A control arm holds the flapper slightly open during run in, allowing the valve to fill from the bottom. This removes the requirement for filling the drill pipe from the top, saving time. Similar to the Model G, the valve fully opens when the drill string is raised, preventing environmental and safety risks associated with having mud on the rig floor. The valve operates as a Model G as soon as the mud is pumped down the drill string. The Model GC helps prevent pressure surges that could cause formation damage.

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: Unless you are using automatic fill Model GC, 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.
