This Economical Float Valve is used for casing flotation and cementing operations in wells with moderate temperature (200℉/93℃) and depth. The valves are primarily designed for use in shallow wells with low bottom hole temperatures and expected low backpressures after plug landing. It can be used with differential pressures up to the collapse pressure of the lightest weight of J-55 casing in the casing size in which it is run.
