ISM Drill Pipe Float Valve

Drilling a well where natural gas pockets exist can be hazardous if not controlled. The high pressure in the pocket can push the drilling mud back up the drill pipe destroying valuable equipment. The ISM - Float Valve Assembly is designed to prevent this hazard from taking place by closing in the event of a back pressure surge. Unlike other similar assemblies, the ISM - Float Valve Assembly is designed for a very long wear life.

Our Float Valve assures continuous control of fluid flow during drilling while providing instant shut-off against high or low pressure.  The fast acting plunger eliminates breakage of a wet joint by opening when the kelly is pulled out of the hole, then closing quickly.  Bit plugging and flowback are prevented with the ISM-Float Valve when adding joints.  Cuttings are prevented from entering the drill pipe.  Expensive downtime and the likelihood of having to pull a wet string is eliminated.  For normal drilling operations, the most economical choice is the ISM-Float Valve, available in 4R, 5R and 6R sizes.
