Float valve Model F
The Model F plunger type valve offers positive and instant shut-off. In normal drilling operations the Model F offers economy
and durability. The piston stops flow-back when making connections and keeps cuttings out of the drill string.
The Model FA offers all the standard features of the Model F float valve with the added feature of a ported
piston, which allows a fluid path through the center of the valve. This feature allows for an automatic partial filling of the drill pipe during run in.
