At US Hydraulics, we offer hydraulic cylinder repair and troubleshooting. We start this process by identifying the prevalent hydraulic issue, like valve sticking, and find a path to repair from there. Here is more information on hydraulic valves and how we fix them:

What Is a Hydraulic Valve?

Hydraulic valves regulate the flow of hydraulic fluid within a system. They control the direction, pressure, and volume of the fluid to confirm the proper functioning of hydraulic cylinders. These valves come in various types, including directional control valves, pressure control valves, and flow control valves. Each type serves a specific purpose in managing the hydraulic system, and their failure can affect the system’s operations.

Common Valve Issues and How We Troubleshoot

Understanding the most common valve problems and how to troubleshoot them can prevent costly downtime. It can also help maintain the efficiency of your hydraulic system. Here are some valve issues hydraulic systems may experience: 

Fluid Contamination

If the hydraulic fluid is contaminated, foreign particles like dirt, debris, or moisture can compromise the valve’s performance. We suggest you regularly check and change the hydraulic fluid to prevent this issue. Consider also using high-quality filters to minimize hydraulic fluid contamination.


Hydraulic valve leakages can occur due to damaged seals or connections. Regularly inspect the system for any visible leaks and replace faulty seals promptly. Tighten connections as you check them to make sure they are sealed properly.

Valve Sticking

Valves may stick due to dirt or insufficient lubrication in the system. Clean the valves regularly, and add proper lubrication to prevent sticking. If a valve continues to stick, it may need to be repaired or replaced.

Inconsistent Operation

If a hydraulic valve is not operating consistently, it may be due to issues with the system’s electrical or mechanical components. Check the wiring, solenoids, and other electrical connections for damage. Inspect the mechanical parts for wear and tear and replace any damaged components.

How We Conduct Hydraulic Valve Repair

When troubleshooting reveals a need for hydraulic valve repair, we approach the process systematically. We begin by identifying and isolating the damaged valves within the hydraulic system to prevent further damage. Here are more of the steps in our repair process:

Disassembly and Inspection

After identifying the issue, we carefully disassemble the faulty valve and inspect each component. We look for wear, damage, or contamination. Our repair technicians then clean the surrounding parts thoroughly to prepare for repair or replacement.

Parts Replacement

If the inspection reveals irreparable damage or excessive wear, we replace the damaged parts with high-quality, compatible components. Using genuine parts helps confirm the longevity and reliability of the hydraulic valve. Instead of replacing the entire valve, we replace or repair only the broken parts. This helps our clients save time and money.


After reassembly, we test the repaired hydraulic valve. We complete these tests in a controlled environment to help make sure the new parts function as intended. These tests check for things like leaks and proper fluid flow. We verify that the valve has consistent operation before we leave the property.

Preventive Maintenance

Scheduling regular preventive maintenance helps prolong the life of hydraulic valves. This maintenance may include hydraulic fluid changes, filter replacements, and inspections. These services are helpful for catching potential valve or cylinder issues before they escalate.
