How to Prevent Check Valve Failure: The Ultimate Guide

A check valve is a device that is used to regulate the flow of fluid through a system. If it fails, it can cause a lot of damage to the system. This article will teach you how to prevent check valve failure from happening and save yourself a lot of trouble.

Common Check Valve Problem

Water Hammer

A pressure surge or high-pressure shock wave, known as a water hammer, may occur whenever a fluid in motion is abruptly required to come to a halt or alter its direction of movement. In most cases, this occurs with swing-type check valves, in which a flow reversal downstream causes the valve to shut suddenly, producing a pressure wave that travels down the pipe. A water hammer may cause damage to pipe fittings, valves, and even valves.

Reverse flow

When a check valve allows water to flow back upstream beyond the downstream side of the check valve, this is known as reverse flow; in other words, there is a flow in both directions via the check valve. This may harm equipment such as discharge pumps because the flow that returns to the pump can force the impeller to spin in the opposite direction, destroying the pump.

Improper installation, maintenance, and assembly

When check valves are not installed, maintained, and assembled correctly, just like with any other piece of mechanical equipment, this may result in damage that is both expensive and time-consuming to repair and, ultimately, failure. The valve has to be orientated appropriately for the piping system during the installation process. It is essential to remember that a check valve operation might vary from one model to another.

Debris In Pipeline

It is possible for debris in the pipe to get trapped in the check valve, causing the valve to become immobilised in either the open or closed position. In addition, debris that is moving at a high rate of speed might disrupt the one-way check valve and cause harm to the internal mechanism. This may result in components of the valve breaking off or being dislodged, which then causes more debris to flow in the direction of the downstream flow.

Preventative Measures to Avoid Check Valve Failure

Preventative maintenance that is performed correctly and consistently is essential for minimising the risk of check valve failure and maximising the valve&#;s lifespan.

• Keeping the pipeline as well as the valves clean and clear of debris is the first and most effective measure that can be taken to prevent a valve from failing. Putting in filters and coverings where they are needed is one way to accomplish this goal. It is also possible to execute routine flushing of the pipe system to remove debris that has accumulated and minimise the accumulation of impurities.

• Lubricating the valves is another efficient strategy that may be used to delay early valve failure. Because check valves are made up of several moving parts, reducing the amount of friction between them by using lubrication may help prolong the life of the individual valve sections, improve the valve&#;s overall performance, and make sure that it operates effectively.
