The invention provides a valve and method for injecting a treatment fluid into a production zone of a hydrocarbon production well. The valve comprises a tubular housing comprising an axial fluid passage, a fluid inlet in fluid communication therewith, and a lateral fluid outlet; a sleeve having a sleeve fluid passage and at least one lateral fluid opening, the sleeve being fixedly arranged within the housing and aligned with the housing fluid passage, wherein the fluid opening is aligned with the fluid outlet; and a piston moveably disposed within the sleeve fluid passage between closed and open positions, wherein the piston when closed blocks treatment fluid flow from the housing fluid passage toward the sleeve fluid passage, and wherein the piston when open permits treatment fluid flow from the fluid inlet through the housing fluid passage, the sleeve fluid passage, and the fluid opening toward the fluid outlet.
