NEOPERLĀ® Check valves Check valves protect faucets and installation systems to prevent the backflow, backpressure or backsiphonage of used water into the pipeline system. They also guard against the potentially hazardous crossover flow between hot and cold systems in thermostatic faucets, for example. This means that hot water cannot get into the cold water pipe or vice versa. Check valves are also available with integrated flow regulators. These not only protect against backflow, but also control the flow rate regardless of the prevailing pressure to the greatest extent possible. Check valves | 37
