Emerson's new flushing ring design
Emerson has introduced a new flushing ring design that is said to reduce maintenance and improve differential pressure (DP) measurement accuracy, while also reducing installation time by eliminating the need for onsite assembly.
The Rosemount 319 Flushing Ring with valve-integrated design is suitable for a range of differential pressure applications. Available in traditional and compact options, the flushing rings provide a process-to-seal connection and allow for faster diaphragm seal maintenance without disconnecting them from process flanges.
Both versions of the Rosemount 319 Flushing Rings come pre-assembled, including the flushing ring, matching valves, and connections, allowing technicians to commission devices faster by eliminating the need to procure and assemble components onsite. The flushing rings are factory leak-tested and, when installed, diaphragm seal maintenance is said to be significantly faster without compromising safety.
Additional features include:
- The Rosemount 319 traditional flushing ring design uses a flow-through cleaning action and can be sized to fit almost any application. Configurations are offered with a choice of ball valves, needle valves or gate valves, and in multiple materials, flange types, sizes, and ratings.
- The Rosemount 319 compact flushing ring is designed to remove residual buildup quickly, cleaning five times faster over 30% more surface area and 50% fewer leak points than other flushing rings. Assemblies accommodate a wider range of applications owing to their smaller footprint, for accurate differential pressure measurement in applications that have limited space for flushing ring installation. Configurations are offered with needle valves and in multiple materials, flange types, sizes and ratings.
“Rosemount 319 Flushing Rings with integrated valve assemblies are designed to eliminate procurement and onsite labor cost,” said Emerson product manager Nicole Meidl. “Products can be commissioned faster and more efficiently, and DP level seal systems can be easily accessed for future maintenance with reduced shutdown timelines. Efficiencies like these reduce risk, cost and complexity for our customers.”
