These Valves Are Designed To Evacuate Lines of Product or CIP Solution

The 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. These valves help to protect pipelines against corrosion by drying process lines after they are cleaned and rinsed. Air drying of lines permits the formation of the protective oxide film. Air agitation thoroughly mixes and blends product – improving product uniformity and quality.

The Air Blow Check Valve can be used in any position, horizontal or vertical. They are easily installed on Ball check Valves or tanks by using a clamp, a gasket, and a mounting ferrule. No other fittings are required.
