Product Description
API Drill Pipe Float Valve with Plunger and Flapper Type
Product Description
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 .
