Plastic Check Valve Non Return Shower Head Valve 10PC/Lot Bathroom Accessory One Way Water Control Connector Valve

Set Include: 10Pcs Shower Check Valves Condition: Brand New Material: POM

Features: Made of high quality material, environmental friendly, non-toxic, safe and durable to use. 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). Applications include faucets and valves for most residential or commercial installations as well as pumps, filters and appliances.

Size(D x H): Type A: 10 x 11mm/0.39 x 0.43 inch Type B: 14 x 16mm/0.55 x 0.63 inch Type C: 15 x 16mm/0.59 x 0.63 inch

Working Principles: 1. In static conditions (no flow) the check valve is normally closed. The spring tension forces the plunger into its seat keeping the check valve closed. 2. In dynamic conditions (flow) the water pressure exceeds the spring tension. The plunger is lifted off its seat allowing water to flow through the valve. 3. In backflow conditions (reversed flow) If the pressure downstream of the valve increases( back pressure conditions) or if the system pressure upstream of the valve decreases( back siphonage conditions) causing the flow to reverse direction, the spring loaded plunger closes and prevents back flow. Friendly Tips: The size is measured by hands, please allow minor error of measurement. Photo color might be a little different from the actual product due to color display of different monitors.
