Purpose
A WJ Valve is designed to hold a certain amount of fluid from draining back in the wellbore. It consists of a fishneck, packing sub, collet, and plunger. It is divided into two categories; cast steel globe valve and bronze WJ valve.

1. Fishneck 2. Shear Disc 3. Plunger 4. Cage 5. Packing Sub 6. Collet
