As new platforms and technologies move from prototype to production, they inherit the same fundamental need: leak-tight sealing and precise, reliable flow control in ever more compact and demanding designs. SFC KOENIG partners with innovators early, applying 40+ years of expertise in expander plug, restrictor, and check valve technology to help emerging platforms meet performance, safety, and reliability targets from day one — supported by custom engineering and setting tool solutions where standard components aren’t enough.
