800ES gas non-return valve tested

Witt Gasetechnik GmbH’s 800ES gas non-return valve has recently been tested by the BAM Federal Institute for Materials Research and Testing in Germany for burn-out safety up to 240bar with oxygen. The 800ES non-return valve, which can also be used with other technical gases including hydrogen, is designed for installation in a gas supply system automatically preventing creeping or sudden reverse gas flow. Applications include cutting and burning equipment, pressure control stations and flammable gas supply pipelines. Installation of this non-return valve can also be carried out in confined spaces. It measures 70mm long with a diameter of 18mm and has a 1/4in NPT thread. It is manufactured in stainless steel. The valve seat and O-ring used are dependent on the type of gas.
