Specifications: Plastic Insert Check Valve 10mm~32mm Non-Return One Way Water Control Connector Applications include faucets and valves for most residential or commercial installations as well as pumps, filters and appliances. 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).
