Product Description
Model F/G Type Drill Pipe Float Valve
The float valve prevents drilling fluids, cuttings and metal debris from flowing back up the drill string. When correctly installed on the drill string these valves provide added blowout prevention.The float valve can be used anywhere from top to bottom of the drill string. It's most common location is in the BHA (bottom hole assembly) which includes the bit, and can include a bit sub, near bit stabilizer, other stabilizers, float sub, cross-over sub, mud motor (top sub), drill collar, and the drill pipe. Multiple float valves can be used in one string, although double stacking is not recommended because of possible damage to the float valve in high pressure situations. Instead, separate the valves in different tool joints.
Drill Pipe (DP) Float valves are available for standard service, H2S - 300°F service (HNBR/HSN) and H2S - 400°F service (Viton.)
