Product Description

TOP-FLO® 62-174R Air Blow Check Valves are designed to evacuate lines of product or CIP solution, and for air agitation of product in tanks and other vessels.

      • The valve helps to protect pipelines against corrosion – air drying of lines permits formation of the protective oxide film.
      • Improves product uniformity and quality – product air agitation thoroughly mixes and blends product.
