NEWCO Check Valves and Backflow Preventers

7 results found that include 7 Products

Check valves and backflow preventer valves help protect potable water supplies from contamination due to the reverse flow of polluted water due to backsiphonage and backpressure. Some valves feature good chemical resistance and are suitable for use in heating applications. Sanitary check valves are suitable for food handling and processing industries to prevent the backflow of liquids. Spring check valves are designed to assist closure pressure to create a positive shutoff. Vacuum breakers help prevent backsiphonage of contaminated water into a water supply and many are suitable for use in hot or cold water service. Backflow preventer test kits allow you to test backflow preventers for correct operation, while backflow preventer repair kits let you perform preventative maintenance to help reduce valve failure. Go to Grainger for the check valves and backflow preventer valves ideal for your specific use.Close
