About Check Valves

Take advantage of discount check valves here at PlumbersStock. Also known as non-return valves, they are useful because they allow fluid to flow in only one direction. In other words, they prevent backflow. They are used in a variety of plumbing and irrigation applications.

Read: What Is a Check Valve?

Features and Applications:

Non-return valves come in all shapes and sizes, but they are relatively small in most cases, and they usually function automatically. Rarely will you find one that is controlled by hand. This valve is handy in a considerable number of applications. However, all types of check valves share the same primary function: preventing backflow. The double ball-check valve is a two-ball/seat combination linked together in the same body to ensure a leak-tight shutoff when blocking the reverse flow.

Check valves are typically used in certain types of pumps, such as diaphragm or metering pumps; they are most commonly used on the pump's inlet and outlet lines. There are industrial check valves, such as those used in chemical and power plants. They are especially useful when several gases are mixed in a single gas line. To prevent gas mixing, a non-return valve is installed in each gas stream.

Then there is the household or domestic appliance; some types of irrigation sprinklers and drip irrigation emitters have water check valves built to stop the lines from draining while the system is off. They can be used in heating systems, hydraulic jacks, and some dishwashers have them. They can also be used in rainwater-harvesting systems that pump rainwater into the main water supply.
