Abstract: A fluid valve comprises a fluid conduit and a flow reducing device. The fluid conduit includes a fluid input end and a fluid output end. The flow reducing device comprises a first fluid passage and is configured to adjust the width of the first fluid passage. The first fluid passage has a narrow width over an extended flow distance that is delimited by internal walls that cause a pressure gradient in fluid passing through the first fluid passage. The flow reducing device further comprises a second fluid passage having a narrow width over an extended flow distance that is delimited by internal walls. The first fluid passage and the second fluid passage are parallel to each other. The flow reducing device further comprises a plurality of damping elements having surface portions parallel to each other. The facing surface portions of adjacent pairs of said damping elements define the internal walls delimiting the first and second fluid passages.
