Hydraulic Valve Repair

We can take care of all your hydraulics including servo and proportional valves, cylinders & pumps.

Our hydraulic valve department is home to over 30 years of experience in the hydraulic repair business! No matter the industry you are in, we can service you and get your hydraulic systems back up and running! ACT is your solution for hydraulic component repair – pumps, motors, valves, servo valves, proportional valves, actuators, cylinders and power units. When we receive your hydraulic valve, we’ll completely disassemble and clean it prior to a full inspection. Once completed, we’ll go ahead and list any worn, broken or missing parts for replacement, followed by a risk-free quote free of charge to you.

Once approved, we’ll re-clean your unit and get it ready for repair. You can expect only the highest quality repair from ACT. We ensure that your unit is completely reconditioned (or replaced) to meet factory specs. After we get your unit reconditioned to meet our quality standards, we put it through our testing procedure.

We are also a distributor for STAR servo valves and can offer direct drop-in replacements for valves that are beyond repair! In addition, we are also a distributor for Yates cylinders and can fully assist you on either the repair or replacement of your plants cylinders!
