Check Valves

Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns, the valve will close to protect the piping, other valves or pumps. Check valves are useful in HVAC systems and water and wastewater applications. They are often placed on the outlet side of a pump to protect the pump from backflow.
