Emerson announced two new technologies for the Crosby J-Series pressure relief valve (PRV) product line. The first is a Balanced Diaphragm, which eliminates the need for bellows in PRVs, while providing balanced operation against backpressure to lower cost of ownership and enhance performance. The second technology is Bellows Leak Detection, enabling remote detection of bellows ruptures in PRVs, with the capability to reduce and accurately calculate volumetric emissions in real-time. Upgrade kits for existing Crosby J-Series PRVs are available for both new technologies, and new PRVs can be purchased with these features pre-installed.
