Secure Drilling SM ServicesGateway <strong>Wireline</strong>-<strong>Retrievable</strong><strong>Nonreturn</strong> <strong>Valve</strong> (<strong>WR</strong>-<strong>NRV</strong>)Features, Advantages and Benefits• Easy access on wireline means the Gateway <strong>WR</strong>-<strong>NRV</strong> can be changed orremoved without tripping the drillstring or killing the well. Eliminating the tripsrequired to retrieve a fixed valve saves valuable rig time.• Designed for high-pressure applications, the valve ensures pressure-controlintegrity, even with extremely high-pressured hydrocarbons.• A large bore ID minimizes friction when pumping gas and fluid into the drillstringfor maximum drilling performance. The valve only restricts flow when fluids orgas travel up the drillstring.• The large bore design does not preclude the pumping of balls or darts, whichprovides options not available with fixed-float valves.SpecificationsGateway <strong>WR</strong>-<strong>NRV</strong> Dimensional SchematicSize(in./mm)AOverallLength(in./mm)BMaximumOD(in./mm)CMinimumID(in./mm)RunningTool(in./mm)PullingTool(in./mm)PressureRating(psi/MPa)2.3158.6717.69449.332.2857.911.3835.052.50 WX63.5 WX2.50 GS63.5 GS10,00068.92.8171.3718.14460.762.7269.091.7544.453.00 WX76.2 WX3.00 GS76.2 GS10,00068.9ACBweatherford.com 2 © 2009-2010 Weatherford.
