The Enardo Series ES-950 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 vacuum relief for normal venting requirements 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%
