Improved Emerson Pressure Relief Valves
New Crosby pressure relief valve solutions
The Crosby J-Series Bellows Leak Detection solution reduces fugitive emissions, providing quick notification of a bellows failure. Emerson.
Emerson is releasing the new 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. Extending the backpressure limit and increasing the Kb factor often permits the use of smaller valves. 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. PRV installations are often difficult to access and in hazardous locations, making leak detection difficult.
