Signs Your Hydraulic Valves Are Breaking Down

Monitoring your hydraulic valves is important to maintain the operation and efficiency of your equipment. Although the valves are built to be tough and durable, they can still start to break down over time. There are a few common signs to look for to determine if the hydraulic valves are starting to break down and require attention.

Unusual Noises

You may start to notice that the valves are making unusual noises as they operate. It’s common to hear knocking and banging noises as the parts are operating, which can become louder over time. Replacing the necessary parts early on is essential to prevent costly component repairs that may be needed in the future if the issue is unaddressed. The equipment will also need extended downtime and won’t be able to operate until the necessary repairs are performed.

Slow Operation

You may notice that the stainless steel valves start to have a slow operation, which can affect your productivity and the operation of the equipment. The longer cycle times require inspecting the parts to determine if they’re still in good shape or need to be replaced due to wear and tear that has developed.


Once hydraulic valves are no longer in good condition, they can cause leakage to develop. Although they’re designed to maintain the flow of the fluid, they can cause the fluid to seep out. You may notice a small amount of oil coming out, which can be addressed by installing new hydraulic valve parts.

High Fluid Temperature

It’s common to have a high fluid temperature once the valves begin to break down. This can start to damage other parts like the seals due to a lack of lubrication that is present as the oil becomes thinner. This issue is often accompanied by a slower operation of the equipment. If the issue is neglected, it starts to reduce the lifespan of the hydraulic fluid and can lead to other issues. You may notice a lower viscosity, which then leads to an increase in the heat load.


Once you understand how hydraulic valves start to break down, it can be easier to know the common signs to look for to determine when they need to be replaced. Installing new valves can restore their operation and can allow you to avoid encountering additional problems with your hydraulic system in the near future.
