tubing-retrievable safety valve (TRSV)

1. n. [Well Completions]
A type of subsurface safety valve that is run and retrieved as part of the production tubing string. The TRSV body is integral part of the completion that enables the internal components to be configured to provide near fullbore access through the valve. An external control line is secured to the running string for connection to a surface-control system.
