Air Blow Check Valves
Air blow check valves are designed to protect pipelines against corrosion by evacuating lines of product or Clean-In-Place (CIP) solutions.
The valve works by air pressure pushing the rubber plug away from the seat. When air pressure is absent, the spring holds the valve closed against the seat, preventing product from flowing into the air line.
Air blow check valves work in a variety of applications including evacuation and/or drainage lines for evacuation of product and air stirring products in pipes, storage tanks, and other equipment.
