Check Valve

Commonly known as one-way valves, check valves are made primarily to block backflow and to protect compressors and pumps. They are common in various industries and applications including natural gas, mining, and municipal water. Their main parts include a cover, body, seat ring, disk, and a hinge pin. They come in different types, like the swing type, lift type, dual plate type, and the stop check valve. The fluid pressure that goes through the pipeline will open the valve. Meanwhile, any backflow will shut the valve. Check valves will promote smooth flow and will shut automatically as pressure declines.
