Check Valves

Check valves are self-activating relief valves that operate entirely by reacting to the flow and pressure generated by the process streams in which they are installed. Also known as one-way directional or non return valves, these devices are designed to allow fluid, air or gases to flow in only one direction and eliminate backflow.
