The valve has a valve body with at least one orifice therethrough. The orifice has a substantially uniform diameter and an upstream inlet part. The inlet part has an enlarged diameter relative to the substantially uniform diameter of the orifice. The valve body is disc shaped with a plurality of parallel orifices placed equidistant from a rotational axis.
