Duo-Chek® High Performance Check Valve

Featuring an innovative dual-plate design, CRANE Energy Flow Solutions®’ Duo-Chek® High Performance Check Valve employs two spring-loaded plates suspended on a central vertical hinge pin. The dual plate and flat seat design improves performance and allows for bubble-tight shutoffs and resilient seats.  Its independent spring action has a maximum deflection of 140° reduced water hammer, resulting in improved valve response and extended product life.

Additionally, this product recently obtained the Shell Supplier Technical Assessment Record (STAR) level 2 rating, and is now listed in Shell’s Technically Accepted Manufacturers & Products (TAMAP) database.  It is capable of operating within the extreme temperature range of +450 degrees Celsius to -196 degrees Celsius, thus can now be implemented in low and high temperature applications globally, including those in the LNG Cycle, like Liquefaction, Storage and Loading, Ocean Transport, Reception, Storage and Regasification.  Other applications for which it is appropriate include: Petroleum Refining, Oil and Gas Production, Petrochemicals, Chemicals, Power Generation, Steel/Primary Metals, Marine, Water and Wastewater, and Pulp and Paper.
