The main function of a check valve is to prevent fluid from going in the opposite direction desired. When the direction is as desired, the check valve remains open, and when the fluid loses speed or pressure, the valve closes, thereby preventing counterflow. The difference between input and output pressures makes the valve open or close.

At Herbe, we have a broad selection of check valves that are appropriate for a myriad of applications, thanks to their different constructions and materials.
