ABSTRACT:
A valve is disclosed for use in suppressing surges of fluid flow therethrough by means of first and second flow paths the former of which has the greater fluid-handling capability but which also is subject to being closed to suppress a surge, while the latter remains open to bleed the surge pressure and effect re-opening of the former for normal flow subsequent to the surge.
