About Our Shop

We’ve built our shop around one thing: industrial repair. With decades of hands-on experience and deep product knowledge, we deliver consistent results.

How We Rebuild This Valve

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.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Diagnostic Testing

Each MOOG 31-154 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our functional testing verifies proper functionality.
