ABSTRACT:
A fluid material flow control valve comprised of a conduit having an inlet end and an outlet end, and a remotely inflatable valving element disposed in the conduit between its inlet and outlet end such that the conduit can be variably opened to fluid flow by variably inflating the valving element and such that the conduit will always be closed to fluid flow when the valving element is deflated such as by intentionally withdrawing the inflating pressure source or through an accidental loss in system pressure.
