ABSTRACT:
A valve includes a housing assembly, a stem assembly and a surge suppression device. The surge suppression device includes an initial flowpath between the valve inlet and the outlet, a primary flowpath between the inlet and the outlet, a first valve assembly and a second valve assembly. The first valve assembly is coupled to the stem assembly and threadably engages the housing assembly and structured to move between a first, closed position wherein the primary flowpath is blocked and a second, open position wherein the primary flowpath is not blocked. The second valve assembly is threadably coupled to the housing assembly and structured to move between a first, closed position wherein the initial flowpath is blocked and a second, open position wherein the initial flowpath is not blocked.
