What can be done to prevent check valve failure?
What can be done to prevent check valve failure? 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. When does reverse flow occur in a check valve? Reverse flow — Reverse flow occurs when the valve permits water to flow back to the upstream side of the check valve; in other words, there is a two-way flow through the valve. This can be detrimental to equipment such as...
