Double Check Valve Suppliers
Double check valve is a backflow prevention instrument designed to protect water supplies from contamination. It has two check valves assembled in series usually with a ball valve or gate valve installed at each end for isolation and testing. Often, test cocks (very small ball valves) are in place to attach test equipment for evaluating whether the double check assembly is still functional. It is suitable for prevention of backpressure and backsiphonage. It is commonly used on lawn irrigation, fire sprinkler, and combi-boiler systems
