Applications:
- The check valve is to prevent the fluid from flowing back and ensure flowing in one way direction.
- It can be used to reduce the loss of fluid suction bacl and to avoid pipe-hammering.
- It is used in the food-processing, beverages, winery, oil, cosmetics,
pharmaceutical and chemical industries.
Operating principle:
- The valve opens when the pressure of the fluid exceeds the spring pressure.While it is closed when the two pressures are equal.A stronger counter-pressure can also make the valve close.
