50+ years of expertise in OILGEAR VX891 Valve Repair

Repair Process

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

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • 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.

Diagnostic Testing

NC Servo operates over a dozen dedicated flow test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using industry-standard fluids including MIL-5606 and Skydrol. Our pre-shipment testing verifies consistent performance.

Maintenance Tips

  • Check system pressure regularly to verify it stays within the OILGEAR VX891 rated operating range.
  • Flush the hydraulic system after any major repair to remove debris before reinstalling the OILGEAR VX891.
  • Keep hydraulic fluid clean and at proper levels for consistent valve operation.
