A check valve — also called a one-way valve, non-return valve, or clack valve — only allows flow in one direction while preventing reverse flow, or flow in the opposite direction. These valves open and close based solely on the hydraulic pressure from the flow of water acting on the valve mechanism.
Check valves are often used in steam lines, condensate lines, water lines, HVAC systems, and chemical feed pumps, to name just a few common applications. These valves are critical components in many situations, as reverse flow can be very damaging to some equipment. Therefore, it’s essential that the symptoms of check valve failure be detected as early as possible to prevent facility downtime and costly repairs.The key to preventing check valve failure and ensuring valve longevity is proper and regular preventative maintenance.
The first and most effective step for avoiding valve failure is keeping the pipeline and valves clean and free of debris. This can be achieved by installing filters and covers where required. Regular flushing of the piping system can also be performed to remove settled debris and minimize the buildup of contaminants.
Valve lubrication is another effective method for preventing premature valve failure. Check valves consist of several moving parts; therefore, minimizing friction between these components through lubrication can extend the life of the valve components, enhance overall performance, and ensure efficient operation.
Finally, valves must be installed correctly and used as directed. Improper valve installation, or using the wrong type of check valve, can reduce the lifespan of the valve. A regular maintenance schedule should also be implemented to ensure that faulty valves are replaced at the first sign of failure.
