These high- and intermediate-pressure automated RSVP-UC valves have been in service for 8 years. Installed in a gas fired plant, these valves have fail-safe actuators with jack-screw override.

With the integration of two powerful movers – both gas engine and steam turbine – the combined cycle plant has the capacity to produce tremendous amounts of power on short notice with its quick start-up time. Quick start-ups, however, can be brutal on a valve population and ultimately cause the break down of surface coatings and destroy packing arrangements.

MOGAS understands the unique challenges of the combine cycle plant and has done extensive research at plant sites to better understand how thermal cycling affects valve components. It was realized that the mechanically bonded coatings, such as HVOF applied Chrome Carbide, had a tendency to crack and flake off causing leak-by and possibly lock-up. Innovations were then made to fuse our coating to the base material creating a metallurgical bonded coating. Since this we have enjoyed flawless performance and extended longevity.
