Norriseal-Wellmark’s butterfly valve legacy began more than 85 years ago with the Mudco Valve Company in Tulsa. In the 1950s, Mudco became part of the W.C. Norris Company and later a founding member of Dover Corporation in 1955. The original D-Series valve evolved into the M-Series, introducing a proprietary O-ring groove that advanced sealing performance. That innovation led to the R-Series butterfly valve, engineered with a cartridge seat and angled disc for longer service life and superior shutoff. This design continues to define the Norriseal Norris valves today. Engineered in the USA. Built for oil and gas, marine, industrial, and HVAC systems. Proven in the field for decades.
