Abstract
A valve comprising a slidable internal shuttle that is shiftable between a valve closed and a valve open configuration is provided. The valve can be configured so that minimal force is required to effect shifting of the shuttle, even though the valve can be of a large diameter. In the valve closed configuration, the shuttle blocks communication between the valve inlet and outlet. Sliding of the shuttle to the valve open configuration permits fluid to flow through the valve. The shuttle can be configured with internal surfaces that provide some or no biasing forces acting upon the shuttle in the valve closed direction.
