FIFFCO Check Valve, also known as non-return valve, one-way valve, is used to allow water to flow through it in only one direction. A hinged clapper remains open with water flowing in one direction, and automatically closes when flow stops preventing back flow. Removable cover allows easy access for inspection and maintenance. These valves are suitable for installation in both horizontal and vertical (with the flow upwards) pipelines.
