Previous commercially available solutions work up to far lower operating pressure or have not been tested at all. This valve may therefore be considered as “one of a kind” when it comes to accident prevention. It is safe and fire-resistant up to the stated pressure limit.This one-time test by BAM is also particularly significant because it makes it far easier for the user to obtain a permit for his gas supply system, which enhances safety and saves costs.
In addition to oxygen, the "800 ES" can also be used for other technical gases including hydrogen. Applications include almost all machinery, pressure control stations and flammable gas pipelines. Any back feeding of gas in these systems could lead to the formation of combustible mixtures and cause an explosion. Gas non-return valves such as the “800 ES” prevent this. They are the only systems capable of automatically preventing creeping or sudden reverse gas flow.
Installation should not present any problems even in confined spaces. The part produced by Witt is less than 70 mm (2.8 inch) long with a diameter of only 18 mm (0.7 inch) and has the commonly used ¼ inch NPT thread. It is mainly made of stainless steel as this is more resistant than brass. The valve seal and O-ring are chosen according to the particular type of gas. With this innovative valve, the manufacturer from Witten is expanding the wide range of progressive safety solutions for virtually all technical gases.
