One-year warranty on all ROSS MC3V1S4 valve repairs

Repair Process

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • 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.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Leak and Performance Testing

With our 13-stand test facility 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 operational testing verifies spec-level operation.

Repair, Rebuild and Exchange Options

Beyond standard refurbishment, we offer specialized overhauls for your ROSS MC3V1S4 unit. Our teardown process includes flow verification and internal inspection, using only replacement replacement components.

Stock Availability

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

Maintenance Tips

  • Check valve alignment carefully to prevent undue stress on internal components.
  • Keep a spare ROSS MC3V1S4 on hand to minimize downtime during unplanned failures.
  • Monitor operating temperatures to identify potential issues before failure occurs.
