Caged Ball Frac
Caged Ball Frac Plug Configuration
The Express Series Caged Ball Frac utilizes a simple Ball / Cage Adapter that houses a ¾” Brass Ball in the upper ID of the plug. When zonal pressure is greater from below the plug, the ball cage allows the lower and upper zones to comingle. When zonal pressure is greater from above, the ball seats thus isolating the zones.
