Application:
A check valve (or non-return valve) is an automatic, self-actuating device installed in piping systems to allow fluid to flow in only one direction, preventing dangerous reverse flow (backflow). It protects pumps, compressors, and equipment from damage, maintains pressure, and prevents contamination in systems ranging from water, gas, and industrial processes to household applications like aquarium pumps.
