How We Repair Your Unit

Each PROPORTION-AIR DR2TFFFN29 undergoes reconditioning — disassembly, parts replacement, reassembly, and bench testing before shipment.

Experience and Warranty

We stock common wear parts in-house, so most rebuilds don’t require outside sourcing. Less waiting, faster turnaround.

No cleaning required. Our repair process includes disassembly and cleaning of all components.

Disassembly and Rebuild Procedure

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.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.

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 operational testing verifies proper functionality.

Repair, Rebuild and Exchange Options

Beyond standard maintenance, we offer specialized reconditioning for your PROPORTION-AIR DR2TFFFN29 unit. Our overhaul process includes flow verification and reassembly to spec, using only replacement replacement components.

Maintenance Tips

  • Conduct thorough visual inspections for wear or leaks during routine maintenance.
