Description
The Type “D” Equalizing Plug is a plug that is designed to hold pressure from below. It can be used in conjunction with many locking devices to bleed off a well in order to perform repairs or replacement of surface equipment. It also has pump through capabilities that would allow an operator to kill a well. A pulling prong is needed to equalize these subs. The prong actuates a secondary valve which allows either fluid bypass or pressure equalization.
