How We Rebuild This Valve

We disassemble every valve, inspect it inside and out, and clean all moving parts. Components that fail inspection are swapped out before the valve is rebuilt and tested.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • 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.
