Abstract
Pressure-reduction devices for fluid systems are disclosed. An example device includes a housing defining an axial fluid passageway between an inlet and an outlet. A first plate is fixed to the housing and positioned in the axial fluid passageway. A second plate is positioned adjacent the first plate in the axial fluid passageway. The second plate is moveable relative to the first plate between a first position to move the pressure-reducing device to a closed position to restrict or prevent fluid flow through the axial fluid passageway and a second position to move the pressure-reducing device to an open position to allow fluid flow through the axial fluid passageway.
