Crosby pressure relief valves improve safety and increase uptime by delivering reliable overpressure protection across a wide range of critical applications.
Emerson recognized 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 with improved performance, greater reliability, and enhanced safety.
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.
