Detail and Assembly drawing of Non Return Valve

The main function of a non-return valve (NRV), known as a check valve, is to allow steam flow in one direction and automatically prevent backflow. In other words, they prevent steam from flowing back to the main header of the boiler, or back to a boiler that has failed or is off line.
