Power generation and energy infrastructure equipment operate under continuous load, high pressure, and demanding environmental conditions, where a single leak or flow deviation can mean lost output. SFC KOENIG expander plugs, restrictors, and check valves are engineered directly into turbines, transformers, and hydraulic systems to deliver leak-tight sealing and precise flow control without adding external components.
Sealing and flow control components built for the hydraulic and cooling systems in turbines and generation equipment, supporting continuous, reliable operation.
Dependable sealing and flow control for the fluid systems in transformers, switchgear, and supporting infrastructure equipment.
