Technical Examples
  1. A valve with the following components: a pipe; an inner sub connected to the pipe; an outer sub connected to the pipe, wherein the inner and outer subs are concentric and define a sub annulus; a conduit between the sub annulus and an inside diameter of the inner sub; a sleeve slideably positioned within the pipe such that in at least one position the sleeve closes the conduit, wherein the sleeve comprises a section of relatively larger outside diameter and a section of relatively smaller outside diameter which define a pressure area on the sleeve between the diameters; and a lock of the sleeve in a position which closes the conduit. A method for controlling fluid flow through a conduit between an annulus defined by inner and outer subs and an interior of the inner sub, the method having several steps: unlocking a sleeve positioned within the inner sub in a first closure position relative to the conduit by sliding the sleeve from the first closure position to a second closure position relative to the conduit; and opening the conduit by sliding the sleeve from the second closure position to an open position relative to the conduit.
