Valves that are known as non-return valves, one way and check valves are all the same type of valves. As defined by the check valves casting, these are all the different names of the same valve, popularly known as the check valve.
Operation of check valves
Check valve is completely different from other types of valve. Their major ability is passing the fluid in any one direction and in that direction only. This function is greatly helpful for a number of applications, especially when it concerns the prevention of overflow. You may know more about the check valve via http://www.apcintertrade.com/en/.

It is important to understand how these function first and foremost. Its operate usually on a two-part system. It has an opening to allow gas to be drawn to the first port. This gas is then transferred with the help of a mechanism that separates the two different types of port.
These ports help in drawing the water from the first port to the second port. This water is then pushed out with an opening, blocking the fluids from reentering the first port.
Different kinds of Check Valves
Now, let us briefly know about the different types of check valves available in the market. There are many types of it's that are common in the industry: swing check, disc check, split disc, diaphragm, and wafer check valve.
These are common valves, used in toilet tanks present in houses and so on. There are no balls controlling the flow.
These are a bit more complex valves that have a disc which is mounted on a spring for functionality. When the water flow stops, the compression of the spring is great. This causes the disc to return to the initial position.
Split disk check valves have a door split in the middle. This door regulates the flow of the liquid in one direction only.
Diaphragm check valves have flexing rubber mechanism. This helps in the regulation of the flow of liquids. It helps in activating a certain pressure on the upstream side of the valve, pushing out the fluid.
