? Check valves are useful in several different types of devices. They stop flooding in water-related devices, such as sump pumps and water heaters. They also protect equipment that can be harmed by the reverse flow of material, such as control valves, strainers, and flow meters. In addition, check valves can stop material from constantly flowing backwards when a device is off, which can save power and protect the parts of the device. Let us see how do Check valve is to work.

? Check valves allow water or other material to flow in only one direction, and stop the material from flowing in the opposite direction. They are installed in pipe lines and do not require any activation from outside. Instead, they sense when the material in the pipes is beginning to move in the reverse direction and plug up the pipe to prevent the material's movement. Check Valve work in a similar way, although it may not contain balls. For example, swing check valves contain a swinging door on hinges that blocks backward-moving material, and split disk check valves contain a folded metal disk that springs open when the material moves backwards.
