Check Valve

Feature

Check valves are used to

Prevent reverse flow: The main function of a check valve is to prevent the reverse flow of fluid (liquid or gas) in a pipeline, ensuring that the flow direction in the system is consistent. For example, in a pumping system, it can prevent the backflow of liquid after the pump is turned off.

Protect equipment: In many systems, reverse flow may damage equipment. Check valves can protect pumps, compressors and other sensitive equipment from damage caused by reverse pressure and flow.

Prevent water hammer: Water hammer is a shock wave caused by the sudden cessation or reverse flow of fluid. Check valves can effectively reduce the probability of water hammer and protect the pipeline system.

Maintain system pressure: In some systems, it is critical to maintain system pressure. Check valves can prevent fluid backflow, thereby maintaining system pressure

Check valves are widely used in water treatment systems, chemical processes, oil and gas industries, HVAC systems, fire protection systems, and various industrial and civil pipeline systems.
