• 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".

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.
