Latch

The Latch is a disconnect mechanism within a subsea test tree system. It can be hydraulically or mechanically disconnected and reconnected. The isolation sleeve within the latch (establishing the seal between the upper and lower halves of the latch) can be externally pressure tested up to the full working pressure of 15,000 psi. Additional features include 17G design and qualification, the use of NACE material, and a shortened design. Up to 22 hydraulic feedthroughs are available, 3 of which can be converted to electrical feedthroughs.
