Dixon Sanitary's air blow check valve is designed to evacuate lines of product or CIP solutions thus helping to protect the lines against corrosion. The valve's fail-safe operation prevents backflow with a simple air-to-open spring-to-close mechanism. Attach and use with Dixon™ sanitary ball check valves, or any quick disconnect clamp configuration, to allow quick assembly and disassembly when replacing filter media, cleaning or inspecting.

A variety of industries have trusted Dixon™ sanitary check valves for many years and the reason is that Dixon Sanitary has the quality valves they need. Dixon™ check valves feature quick disconnect clamp ends for quick easy cleaning (other ends are available). Check valves are used for sanitary, as well as industrial applications, to prevent backflow.

• Spring Check Valves are designed to prevent reverse flow. Concentric valves are available in 1/2" - 4".
• Ball Check Valves are used where full flow and low pressure drop of product during process is required. When the flow of product is reversed, the PTFE ball rolls back and seats, thus preventing backflow. Sizes are available from 1-1/2" - 3".
• Air Blow Check Valves are used to clear lines of CIP solutions or other products. Sizes are availble from 1" - 4".

Bradford Fittings maintain the 3A standard. The 3A Sanitary Standard was created by the dairy industry as a voluntary benchmark for product performance and sanitary safety. The standard, collaboratively developed by a group of processors, suppliers, regulatory officials and sanitation specialists, is generally accepted by federal, state and local regulatory authorities.

Bradford Check Valves have earned the 3A symbol, which requires an annual assessment to make certain each product conforms in all respects to the published standard. Bradford Check Valves carrying the 3A symbol conform to the 3A sanitary standards for fittings for milk and milk products (#63-03). Dixon Sanitary is proud to be a participant in the 3A program.
