NC Servo operates independently, so we’re not tied to manufacturer delays or restrictions. That means more flexibility when your system is down.

Disassembly and Rebuild Procedure

Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Testing and Bench Verification

Each MOOG 85-187 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our operational testing verifies spec-level operation.
