Resilient seated wafer style 

Norris resilient seated wafer butterfly valves are used in applications up to 285 pounds of working pressure (150 ANSI) and are lighter and more cost-effective than metal seated options. Their unique sealing design is field proven to provide longer seat life than comparable competitor resilient seated designs. Wafer options are typically used with smaller valves and in lower pressure applications compared to lug-style designs.
