The UltraFlow circulation valve has been field proven over thousands of wells. It is used for selectively shutting off circulation and allowing pressurization of the work string. Once placed, a ball is dropped from surface to the ball seat. Pressure is applied allowing the sleeve to slide, permanently closing the circulation valve. Hydraulically set packers can then be pressurized for setting.
