Drillmax - Model GCA -Full Flow Flapper Type Float Valve for Automatic Fill with Carbide Insert Port
The Model GCA is identical to the Model GA but adds an automatic fill feature that permits automatic filling of the drill pipe from the bottom and measuring differential pressures from the surface. The Model GCA 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 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 valves. Double stacking is not recommended unless using a Model GS Float Valve.
