What is a Check Valve?
Check valves are safety fittings that prevent fluid from flowing back in fluid transfer systems. There are many types of check valves that can be selected based on system requirements and other criteria. The main factors considered when selecting a check valve are pressure loss, closing feature, and costs.
Check valves are valves that allow fluid to flow in one direction only. These equipment, provided with ball, spring or conical structures, are used for different reasons in different installations. In systems where fluid flow in the reverse direction, such as LPG-powered vehicles, would negatively affect the system operation, check valves ensure system stabilization, while in hydraulic systems, they prevent the decrease in pressure created by the fluid return.
