Description
When the string is retrieved from downhole there can often be fluid trapped between two closed valves that may be under pressure. The Metrol Drain Valve placed between these valves allows a safe and controlled method of bleeding off this trapped pressure and, if desired, collecting the fluid in a sample chamber. The valve allows for the installation of a high pressure needle valve assembly with a gauge monitoring the internal pressure prior to bleed off. A bulk sample can be removed at this point if required.
