R.E. Mason’s Mechanical & Valves Services team, , in collaboration with the customer, pinpointed the design of the Power Boiler Feedwater Control Valve as a cost savings opportunity. The mill replaced the entire feedwater control valve trim (cage, plug, and seat ring) every two years. Historical repair reports described significant trim damage, making the trim beyond repair and causing costly replacements.
Further investigation with the customer’s operations team revealed that the feedwater process control loops experienced high variability and a lack of control to the desired setpoint. R.E. Mason’s engineering team, in partnership with Emerson’s Fisher factory team, found a misalignment between the valve characterization and the process conditions that caused excessive loop instability

R.E. Mason and Emerson engineered a characterized cage design with the proper process control range to retrofit the existing valve. This eliminated the need to replace the entire valve assembly at a six-figure cost.
