Since 1986, Sullivan Process Controls has been driven by a simple but powerful principle: our customers always come first. This unwavering commitment has transformed a small family business into one of the fastest-growing names in control valve technology, earning the trust of many leaders across a wide platform of industrial end markets.
What started as Sullivan & Sons surplus instrumentation business in 1986 has evolved into a comprehensive control valve technology company, but our core values remain unchanged. Every decision we make is guided by one question: “How does this better serve our customers?”
In 2019, a seasoned team of valve industry professionals acquired the company, bringing deep technical expertise and a shared vision of customer-first excellence. This leadership team, drawn from several major manufacturers, understood what the industry needed: a company that combines technical innovation with responsive service.
Our rapid growth isn’t accidental – it’s the natural result of delivering on our promises. This consistency continues to earn us new customers while retaining existing customers across every major industrial sector year after year.
Our leadership team brings unparalleled expertise from across the control valve industry.
