Repair Process

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

NC Servo Tech operates over a dozen dedicated flow test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using standard test fluids to match your operational needs. Our operational testing verifies consistent performance.
