The Premium Tubing Drain Valve allows for the tubing string to be drained prior to tripping, avoiding problems associated with pulling a “wet string”.
The Premium Tubing Drain’s shear value is easily adjusted by simply adding or removing shear screws. The Premium Tubing Drain is activated by increasing the tubing pressure, causing the sleeve to shear the shear pins and open the large drainage ports to the annular space above the pump.
This simple design allows for easy redressing with a Premium Tubing Drain Valve Repair Kit.
