Description
AlfaInject screen works as a injecting flow control device, which is provided by creating additional hydrodynamic resistances to the movement of the pumped fluid. The valve is opened by creating an overpressure in the range of 0.5-2 MPa ± 10% in the base pipe. In the absence of overpressure, the valve is closed. The valve assembly includes an erosion-resistant insert and ball, a pressure spring, and a valve cover with fluid injection ports.
