Founded in 1948, Proconex has been a steward of process control excellence since America’s progressive era. It all started at Walnut Street in Philadelphia, PA, where Clifford B. Ives & Co. was officially founded as the first Fisher representative. Focused on gas regulators and ball valves, and pioneering computer technology, it fundamentally advanced engineering in the 20th century.

The business evolved significantly in 1979 when operations moved to King of Prussia. This relocation marked a turning point, as C.B. Ives & Co. formed Proconex's System Engineering Group and delivered its first-ever system, DC2, to P.H. Glatfelter. Within a decade, major industry shifts reshaped the landscape. Fisher Controls sold its business to Emerson Electric for USD 1.40 billion. Shortly thereafter, John Weekley purchased C.B. Ives & Co. and renamed it Proconex. This ownership shift sparked rapid growth.

Proconex acquired Herron Valve & Instrument, formed Valspec, and opened a division in Puerto Rico. We relocated our headquarters to Royersford, PA, where we operate today under our CEO, John Otte. Through these strategic moves, we’ve established ourselves as the premier provider of process automation control systems, valves and control devices, and related technologies across the Mid-Atlantic region.

Proconex looks to our legacy as a guiding light, not a story of the past. Our history is rooted in process innovations and business collaboration shaped by the needs of our customers. Looking ahead, we pledge to stay at the forefront of process control innovation, continuing our legacy of providing breakthrough solutions that optimize operations in major, world-shaping markets.
