Check Valve

One kind of valve used in plumbing systems to stop backflow is the check valve. It only permits one direction of fluid flow, and when the fluid's direction changes, it immediately closes to halt the reverse flow. Check valves are essential for preventing backpressure-related damage to pumps, compressors, and other equipment. They are available in multiple designs, such as swing, ball, and diaphragm varieties, each appropriate for distinct fluid kinds and purposes.
