The SC Tension Unloader provides a
means of equalizing tubing and annulus
pressures when used with a tension
packer. It also serves as a by-pass to
allow fluid to pass through the mandrel
of the packer while running the tubing
string in and out of the well.
Special Features
> Apply set-down weight to open, and
tension to close
> Unloads pressure from either direction
> May be run in open or closed position
> Bonded seal allows repeated opening
> Transmits torque for packer operations
