PROJECT DESCRIPTION

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 .The port also permits partial automatic fill
during run

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 .The port also
permits partial automatic fill during run in .
