Application Examples

  • Protect drinking water from contamination by backflow resulting from gravity, backsiphonage or backpressure (e.g. Hose connected kitchen spray or shower hand spray).
  • Protect sensitive equipment against possible damage or contamination resulting from a reversal of flow direction (e.g. water meter, pump or filter).
  • Hold water in a system or pipe after the flow has been turned off to prevent drainage or facilitate restart (e.g. pumping systems).
  • Prevent crossover flow in systems with unequal line pressures (e.g. cold and hot water inlets in thermostatic mixers).
  • Reduce the risk of backflow or leakage in case of valve failure (e.g. solenoid valve at the inlet of an appliance).
  • Allow complex systems to function properly by ensuring unidirectional flow (e.g. multi-zone heating system or booster pumps).


All NEOPERL® check valves are designed to be used exclusivly in clear water applications that generally utilize in-line construction.
