Drillmax 1540200 4R G Float Valve

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. Baker/Forum Part # 480154200 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 val
