An apparatus for bi-directionally regulating flow of an actuation fluid includes a conduit and a plurality of baffles. The conduit includes a conduit flow channel that extends longitudinally along a centerline between a first conduit end and a second conduit end. The baffles are sequentially non-coaxially arranged in the conduit. Each of the baffles includes a baffle flow channel that laterally tapers and extends, in a longitudinal direction towards the second conduit end, from a first baffle end to a baffle orifice at a second baffle end. The first baffle end is connected to the conduit, and extends laterally across the conduit flow channel.
