Abstract
In a plate valve, particularly a cone spray valve, the valve gap, or respectively, seal gap (,) which is present in the open condition is not designed with parallel faces, but with cross-sectional areas which remain the same given increasing radius. This approach applies to a set from the interior outward. The advantage consists in the avoidance of cavitation and in the achievement of a low closing force for sealing the valve.
