Check valve is segined to prevent fluid from flowing back and ensure the flow to one way direction.
It can be used to reduce the loss of fluid back suction, avoid ingpipe-hammering.
It is used in the food-processing, beverages, winery, oil, cosmetics,
Pharmaceutical and chemical industries.
The valve opens when pressure of the fluid exceeds the spring pressure. While it is closed when the two pressures are close equal. And stronger counter-pressure also makes the valve close.
