We offer major savings on repairing hydraulic, servo, and proportional valves over the high cost of OEM replacements.
Brands We Service
Precision Valve Restoration
Our technicians are experts in restoring the precision and performance of all types of industrial valves. Each valve undergoes a rigorous testing process on our custom-built test stands to ensure it meets or exceeds OEM specifications before it's returned to you.
- Servo & Proportional Valves: Dynamic testing, coil rewinding, calibration, and null adjustment.
- Hydraulic Valves: Spool and sleeve replacement, seal replacement, and full pressure testing.
- Comprehensive Testing: Flow-testing and system tests to guarantee performance upon installation.
Diagnosing Common Valve Failures
We address the root causes of valve malfunction to ensure a lasting repair.
Internal & External Leaks
We replace all worn seals and O-rings and re-machine sealing surfaces to stop performance-robbing leaks.
Sticking Spool
Contamination is a key cause of failure. We perform a full ultrasonic cleaning and flush of all internal components.
Electrical Faults
Our technicians test and repair or rewind coils, LVDTs, and connectors on servo and proportional valves.
Pressure/Flow Issues
We test valves on our custom stands to diagnose and correct issues with pressure gain and flow control.
State-of-the-Art Valve Testing
Repairing a valve is only half the battle. To guarantee performance, each valve must be tested under conditions that simulate its real-world application. Our custom-built hydraulic test stands allow us to verify every aspect of a valve's function.
- Dynamic Performance Testing: Our test stands allow for dynamic analysis of flow, pressure, leakage, and response time.
- Detailed Performance Report: Every repaired servo and proportional valve is returned with a report detailing its performance on our test stand.
Our Valve Repair Process
Disassembly & Inspection
Each valve is completely disassembled. All parts are cleaned and inspected for wear against OEM specifications.
Lapping, Honing & Repair
Spools are reworked, sleeves are honed, and all worn seals are replaced. Any electronic repairs are completed.
Assembly & Dynamic Testing
The valve is reassembled and mounted on a test stand to verify pressure, flow, and leakage meet OEM standards.
