Freudenberg NOK Sealing Technologies SO3N50 Valve Body Seal Ring

Freudenberg Sealing Technologies (formerly Tobul) valve body seal ring provides enhanced durability while meeting increasingly stringent performance criteria in regards to leakage and low emissions. Valve seals have an impact on the main functions of valves, which are to control flow and prevent leakage. Valve seals are critical in preventing the escape of the liquid or gaseous media in the valve such as the fugitive emissions of volatile compounds, release of hazardous or toxic media (gases or liquids), or leak of corrosive compounds into the environment.
