What is the AOGV?

The AOGV (Add-On Gate Valve) is a patented mechanical isolation tool that creates a secure barrier between two flanges in a live process system. It allows safe isolation of pressurized sections without shutting down operations. The AOGV is a temporary solution; once the job is complete, it’s removed, and the flange is restored to its original condition.
