Subsea retrievable insert with choke valve and non return valve

摘要

The disclosed embodiments provide a flow control insert having both a choke valve configured to control flow and pressure through the system and a check valve disposed along a fluid flow path along which the fluid flows. In accordance with the present embodiments, the flow control insert couples together the choke valve and the check valve, and the flow control insert is independently insertable and retrievable relative to a flow control housing.
