Drillmax - Model DrillmaxPro 10K G -Full Flow Flapper Type Valve

Designed for abrasive drilling fluids. The more robust flapper closes rapidly to prevent cuttings from entering the drill string when flow stops and acts to assist Blow Out Prevention (BOP) equipment in maintaining control over pressure in the line. Model G features an investment cast flapper that is quick opening, for 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.
