3 7/8" x 15000 psi Needle type full bore drain valve
Needle type drain valve
The full bore drain valve is used to drain the volume fluid and release pressure when string testing finished. After the
test string comes out of the well, attach the lines and sample bottles to the drain port of the drain nipples. Then open
the drain port, sample can be got.
Structure
When pressure controlled single shot safety circulating valve and the tester valve are closed, a large volume fluid sample are trapped between the two valves.
Features and Benefits
• Allows pressure trapped between two closed valves to be relieved in a controlled manner
• Used to recover large volume fluid samples
