Nordson Model A7A color-change valves deliver fast and reliable color-change performance for improved productivity and maximum operating efficiency in both circulating and non-circulating systems. They respond to pneumatic signals and feature a carbide ball and seat for positive shut-off and long service life when used in abrasive coating applications. The A7A valves can be used with custom-designed manifolds or are available in standard Nordson color-change manifold configurations for circulating and non-circulating systems.
