Vital Valve is a proud check valve manufacturer and supplier that provides industrial check valves in various configurations and materials, including bronze, steel, and iron valves. check valves are used to ensure that gases and liquids are flowing in one direction only. They essentially prevent the process flow from reverting, which forces the valve to close. check valves are needed to stop backflow and protect rotating equipment and mechanical devices from the sudden backflow surges that may occur. Our check valves are industry approved for a wide range of applications, from oil & gas to pulp & paper.
