Rebuild Steps

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.

Testing and Bench Verification

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 operational testing verifies spec-level operation.
