<p>A pneumatic valve (100) including a first port (150) and a second port (155) is provided according to the invention. The pneumatic valve (100) includes a valve mechanism (101) in fluidic communication with the first port (150) and the second port (155). The valve mechanism (101) is configured to receive a pneumatic control signal via the first port (150) and advance to a next valve actuation state of a plurality of predetermined valve actuation states upon receipt of the pneumatic control signal. The plurality of predetermined valve actuation states provides a plurality of predetermined flow profiles between the first port (150) and the second port (155).</p>
