Patent ID: 8678350

Claim:
A valve comprising: a first tubular member having a plurality of axially spaced first ports extending through a wall thereof; and a second tubular member having at least one second port extending through a wall thereof, being at least partially radially aligned with the first tubular member, the first tubular member and the second tubular member being sealably connected at an interface therebetween, the second tubular member supporting at least one sealable member formed of a first deformable portion capable of slidably sealingly engaging the first tubular member, and a second deformable portion of the second tubular defining longitudinal movability of the at least one sealable member relative to the plurality of axially spaced first ports to selectively allow, choke or prevent flow between fewer than all of the plurality of axially spaced first ports and the at least one second port, the first deformable portion and the second deformable portion being configured to upon axial compression thereof cause the first deformable portion to deform and set the at least one sealable member into sealing engagement prior to deforming the second deformable portion.
