Abstract
A frac valve can include an outer housing with at least one port which provides for fluid communication between an interior and an exterior of the outer housing, and a sleeve releasably secured against displacement between a closed position in which the sleeve blocks flow through the port and an open position in which flow through the port is permitted. The sleeve may be press-fit in the outer housing as a result of the displacement. A method of operating a frac valve can include connecting the frac valve in a tubular string, and displacing a sleeve of the frac valve between closed and open positions. The displacing step can include deforming the sleeve and/or an outer housing of the frac valve, thereby preventing relative rotation between the sleeve and the outer housing.
