Repair Process

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Diagnostic 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 operational testing verifies spec-level operation.
