Check valves, non-return or one-way valves, allow liquid or air to flow in only one direction. Manufacturers make them in a wide range of sizes and types. Varieties of applications use them to prevent costly or even dangerous backflow. Even though many everyday applications use check valves, the basics of check valve operation are not always clearly understood. In this post, I will briefly review some basics of check valve function. I also include descriptions of some of the most common miniature check valve designs used for gas and liquid flow control.
Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps, the most common type of water pumps, are not self-priming, and therefore check valves are essential for keeping water in the pipes.
If the check valve is stuck open, the pump runs and pumps just fine; however, it won’t prevent backflow or flooding.
Check valves are the simplest form of hydraulic devices in that they permit free oil flow in one direction and block oil flow in the opposite direction. Check valves may also be used as a directional or pressure control in a hydraulic system.
Check the valve for debris by tapping its side with the handle of a screwdriver. A rattling sound means the check valve is fine, but inconsistent grinding or squeaking indicates that the valve is stuck on some form of debris.
‘ The main purpose of a check valve is to prevent backflow in the system. Figure 1 shows an example of a check valve. A check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve.
