Lock Mandrel for Safety Valve

Lock Mandrel

The BGI lock mandrel is a top no-go style lock. With a no-go shoulder located just below the locking dogs, this lock will land and lock flow control devices in the corresponding seating nipples. Lock selection should be compatible with the size and model designation (based on designed pressure rating) of the selected seating nipple. BGI’s Locking Mandrels are fully compatible with Baker’s Model “AF” No-go Nipples and can be run with a Model “A” Running Tool and model “D” Probe.
