Hydraulic Valve Repair

What Are Hydraulic Valves, and How Do They Work?

Valves are an important component of essentially every kind of hydraulic application. Hydraulic valves serve the important function of directing and regulating the flow of vital fluids to all key areas of the system, including hydraulic pumps, actuators, cylinders, and motors. They can be controlled either manually or automatically, and can be activated by physical, mechanical, electric, hydraulic, or pneumatic means. In industrial applications, hydraulic valves are typically engineered to be able to withstand extremely high levels of fluid pressure; many hydraulic systems involve pressures reaching 3000 psi or greater!

There are many types of industrial valve styles and designs, many of which are common to other types of valve applications as well. These include butterfly valves, ball valves, bypass relief valves, check valves, needle valves, diaphragm valves, plug valves, diverter valves, regulating valves, and more. In terms of broader categories, hydraulic valves are typically characterized in one of three groups: pressure control valves, flow control valves, and directional control valves.

What Are Some Symptoms of Hydraulic Valve Failure?

Some common issues that often lead to hydraulic valve problems include faulty seals, hardware issues, faulty spring assemblies, or spools that are in need of service. But short of checking each and every individual valve within your hydraulic system (assuming you even know how to do that), how do you know whether a valve issue may even be the problem? Great question! Here are a few likely signs of hydraulic valve failure:

System won’t reach the correct pressure

If your system won’t reach the required pressure, this could be a sign of valve failure. In some cases, this could be fixable – it could simply mean that your valve (or valves) was calibrated to the wrong set pressure and is releasing early. If that doesn’t fix the issue, and it seems like every other part of your system is functioning normally, then your pressure relief valves may simply need to be changed.

System is operating above the prescribed maximum pressure

When (or if) your system builds up above maximum recommended pressure for safety, relief valves should open to let off some built-up pressure. But if your system is above pressure and your valves aren’t being released, this often means there’s a problem with one or more of the valves themselves. As mentioned above, this could just be a calibration issue, or it could mean that your valves have simply failed and require replacing.

Valve with a visual leak, or a pressure valve that displays no pressure at all

In the first two cases, it may not always be easy to see the problem at the valve source itself. But if one or more of your valves are visibly leaking, there can be no doubt where the issue lies. In other cases, you may not be able to see the actual leak, but you can still know it’s there whenever a pressure valve displays no pressure at all. In cases like this, one of three things has likely happened: either the valve has a loose fit, the spring is broken, or the balance hole has become plugged. In either case, prompt service is required in order to restore your hydraulic system to its proper operating condition.
