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
