How We Rebuild This Valve

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

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance 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.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Leak and Performance Testing

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our pre-shipment testing verifies consistent performance.
