Sullivan Process Controls Commitment to Quality

The management and employees of Sullivan Process Controls are committed to providing our customers with reliable products and exceptional quality. Our goal is to have zero defects in manufacturing and to build quality and reliability into our products and services through excellence in design, workmanship, and quality control, as well as through our continuous improvement process.

Sullivan Process Controls technicians use world-class technology during the testing and calibration procedures of all process instrumentation and control valves.

A partnership with an independent flow lab enables each coriolis flow product to be tested and certified by technicians using precision calibration and flow equipment. Also, as the only accredited aftermarket MicroMotion® meter calibration facility in the USA, the lab we exclusively use is uniquely qualified to calibrate any coriolis meter.

We truly have a commitment to excellence for all our control valves and process instruments. Our remanufactured valves are disassembled, sand blasted and powder coated. All soft parts, such as diaphragms, packing gaskets, and o-rings are replaced prior to reassembly. Gasket surfaces are machined back to OEM specifications and trim is either repaired or completely replaced. Lastly, all of our control valves are calibrated and tested to meet industry standards.


The emphasis on quality is evident through the processes, procedures, and controls we implement to ensure a precise and reliable product at a fraction of the cost.


Sullivan Process Controls LLC. (dba Sullivan and Sons Inc.) is proud to be officially certified for the scope of Design, Manufacture, Assembly and Testing of Control Valves used in Compressible, Incompressible, and Vapor Fluid Applications.
