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.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Teardown: Every valve is disassembled for internal inspection.
  • 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.

Hydraulic Testing Process

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 consistent performance.
