Emerson’s Crosby brand has introduced two significant advancements in pressure relief valve (PRV) technology since 2022. The Crosby Balanced Diaphragm innovation eliminates traditional bellows, ensuring reliable operation against backpressure while reducing maintenance costs and improving safety. Complementing this, the Bellows Leak Detection system provides instant rupture alerts, enabling faster maintenance, lowering emissions, and facilitating root-cause failure analysis through event logging.
Diverse Product Line Caters to Demanding Industrial Applications
Crosby’s current overpressure protection portfolio includes three key product families. The J-Series handles multiple media types including air, gas, steam, and liquids. The Omni-Trim series offers additional thermal relief capabilities. The H-Series PRV, specifically designed for power industry applications, recently saw its operational limits expanded beyond 7,250 psi and 1,200°F, making it suitable for extreme conditions in economizers, steam drums, and superheaters.
Emerson Commits to Industry Leadership in Safety and Sustainability
Judson Duncan, president of Emerson’s pressure management business, emphasized the company’s ongoing innovation efforts. “Our continuous product enhancements reflect Emerson’s commitment to regulatory compliance and customer satisfaction,” Duncan stated. “These advancements position Crosby to lead the industry toward safer, more sustainable operations for generations to come.”
Technology Innovations Address Critical Industry Challenges
The 2022 introductions specifically target two persistent industry pain points: the reliability limitations of bellows-based systems and the need for faster failure detection. The balanced diaphragm design addresses the first by removing a common failure point, while the leak detection system transforms maintenance from reactive to predictive, potentially preventing catastrophic failures.
Future-Focused Engineering for Next-Generation Safety
With these technological leaps, Emerson’s Crosby brand demonstrates its 150-year legacy of safety innovation. The company’s focus on higher pressure capabilities, broader temperature ranges, and smarter detection systems reflects the evolving needs of modern industrial operations, where equipment must perform reliably under increasingly demanding conditions while meeting stricter environmental standards.
