About This Product
The Workover Solutions Guardian System is an on-demand set of contingency dual flapper check valves that can be run in the tool string as a backup well control device. It is run in the passive mode and remains as such until activated by dropping a 1” ball which is then captured within the tool to not interfere with ball drop activated tools run beneath. Furthermore, the Guardian will allow for the passing of up to a 3⁄4” ball through the assembly for activation of tools below when desired without adverse effect.
