If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

Rebuild Steps

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

  • 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.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

Testing and Bench Verification

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our pre-shipment testing verifies proper functionality.

Performance Data

Every PEGASUS 120AB we service is tested under operating environments. Our diagnostics verify performance against published specifications. Specification sheets and Technical diagrams are available for purchase upon request.

Repair, Rebuild and Exchange Options

Beyond standard maintenance, we offer specialized overhauls for your PEGASUS 120AB unit. Our overhaul process includes leak testing and disassembly, using only replacement replacement components.

Parts and Inventory

With over 17,000 valves in stock, we can often provide faster turnaround by sourcing parts in-house rather than waiting on OEM lead times.

Maintenance Tips

  • Schedule preventive maintenance intervals based on duty cycle, not just calendar time.
  • Replace inline filters according to maintenance schedules to maintain proper flow rates.
  • Store spare PEGASUS 120AB valves in a clean, dry environment to prevent corrosion and contamination.
