Emerson is celebrating the 150th anniversary of its Crosby line of pressure relief valves (PRVs), marking a significant milestone in the history of PRVs and overpressure protection products. Crosby technologies are field-proven and engineered to meet the latest regulatory standards.

Current Crosby offerings include:

• J-Series – Proven technology providing reliable overpressure protection in various applications, including air, gas, steam, vapor, liquid and two-phase media. Used extensively in the oil and gas, refining and chemical industries.
• OMNI-TRIM – Solution for overpressure protection and thermal relief applications in air, gas, vapor, liquid and steam applications. A straightforward design makes it ideal for refineries, chemical and petrochemical plants, power plant auxiliary systems and pulp and paper mills.
• H-Series – High-performance PRVs for overpressure protection in power industry steam safety applications, including economizers, steam drums, superheaters, reheaters and more.

Emerson is continuously developing new valve technologies based on the company’s deep experience in critical service applications. For example, Crosby Balanced Diaphragm technology eliminates bellows in PRVs, ensuring reliable, balanced operation against backpressure. This innovation reduces maintenance costs, improves performance and enhances safety with its robust design. In a related development, the world’s first Bellows Leak Detection solution provides instant notification of ruptures to enable prompt maintenance, reduce fugitive emissions and provide event logging for intelligent root cause failure analysis — enhancing productivity and environmental protection.

All these overpressure protection products are field-proven technologies, engineered to meet the latest user demands.

“Emerson remains committed to innovation and excellence, continuously enhancing its range of overpressure products to meet and exceed the evolving needs of end users,” said Judson Duncan, the president of Emerson’s pressure management business. “With a steadfast dedication to regulatory compliance, safety, and customer satisfaction, Crosby is positioned to lead a safer, more sustainable industry over the next 150 years.”
