The Solution

IMI CCI already had numerous severe service valves installed at the plant on other applications, consistently exceeding customer expectations. This confidence in IMI CCI products resulted in the customer calling on the IMI CCI team to identify a solution for their recirculation valve problem. A review of the actual process conditions, rates of failures, and trim exit velocity calculations resulted in IMI CCI offering the 100DR solution for the application. The 100DR valve eliminates trim and body erosion through DRAG® technology, limiting trim exit velocity and the high thrust pneumatic piston actuator allows for tight shutoff. The DRAG® disk stack’s discreet tortuous flow paths are designed to limit the trim exit velocities to 70 feet per second or less as per ISA guidelines. Further, the 100DR design features a pressurised seat plug design offering MSS-SP-61 tight shutoff, equivalent to a block valve in closed position to eliminate any valve leakage.

The customer purchased six IMI CCI valves to replace the competitor valves installed in the affected units. The installed IMI CCI valves have reduced the auxillary power consumption of the electric pumps, increased pump efficiency and reduced the total cost of ownership of the system for the customer.​
