| Structure:G type, F type | Application:Well Drilling |
Float valve is one of necessary tool for oil drilling, it consists of float valve sub and float valve, The main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt. When the well blowout or kick, the valve cover of float valve turn off the bore automatically, it will prevent well blowout accident. The working pressure of float valve is supposed to be 5000psi or 10000psi.
Model F Plunger Type Float Valve 1F2R-5F6R for Assembly Model F
The Model F Float Valve is a plunger-type float valve that provides a positive instantaneous shut off,providing constant fluid control while drilling,The model F is a reliable and the most economical selection under standard drilling operations.
Model G Flapper Type Float Valve 2F3R-5F6R for Assembly Model G
The Model G is a flapper-type float valve that,when opened ,offers unrestricted bore through the float valve.The uniquely designed flapper closes rapidly to prevent cutting from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control.
Model FA Plunger Type Float Valve 1F2R-5F6R for Assembly Model FA
The Model FA Float Valve has a special port running through the plunger of the float valve,This valve is used when monitoring the bit head for gas pressure and allowing differential pressure measuring when required.
Model GA Flapper Type Float Valve 2F3R-5F6R for Assembly Model GA
The Model GA Float Valve is indistinguishable from the Model G with the exception of a tungsten-cabide insert in the flapper valve,The insert has a quarter-inch orifice through the center that allows for differential pressure monitoring .
