The Enardo Series ES-851 represents the latest development in high performance enhanced sealing tank venting products with a leakage rate not to exceed 0.
1 SCFH at 90% of the set point. This valve provides pressure or vacuum relief for applications that require vapors to be piped away rather than released to the atmosphere while maintaining a safe internal working pressure and reducing fugitive emissions by a factor of up to 10 times less than similar valves that conform to the industry standard leakage rate of 1 SCFH at 90%
