Claim:
A short stroke valve for regulating the flow of a fluid, the valve comprising: a housing defining a fluid inlet and a fluid outlet; a flow control assembly disposed within the housing between the fluid inlet and the fluid outlet, the flow control assembly including at least first, second and third cages which are disposed in spaced relation to each other and each define at least two flow passageways configured to dissipate energy in a fluid flowing therethrough; and a plug disposed within the housing and reciprocally moveable between closed and open positions relative thereto, the plug comprising at least first, second and third plug lobes which are disposed in spaced relation to each other; the first, second and third cages and the first, second and third plug lobes being sized, configured and positioned relative to each other such that the first, second and third plug lobes will simultaneously block the flow of fluid through respective ones of the first, second and third cages when the plug is in the closed position, and will allow for the simultaneous flow of fluid through the first, second and third cages when the plug is in the open position, the plug being configured such that at least some fluid will flow therethrough between the first, second and third lobes thereof to reach the second and third cages when the plug is in the open position.
