The PetroQuip Pump-Out Auto-fill Sub provides a means of the automatic filling of the tubing while running the tubing downhole. The proprietary design allows annulus fluid to fill the tubing without plugging while providing a reliable seal when pressure is applied from the tubing side. The number of times the tubing is tested is not limited by the internal design of the valve. Once the internal pressure exceeds the shear value the piston closes and permanently locks out the automatic fill feature.
Available in 3-1/2”, 4-1/2”, 5-1/2” and 7” sizes
