22 June 2009

800ES gas non-return valves from Witt, the gas safety, control, mixing and analysis equipment supplier have been tested by BAM Federal Institute for Materials Research and Testing in Germany for burn-out safety up to 240 bar (3,481 psi) 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 is easily carried out even in confined spaces. It is less that 70mm long with a diameter of 18mm and has a ¼” NPT thread, also it is manufactured in stainless steel, which is more resistant to wear than brass. The valve seat and O-ring used is dependent on the type of gas.

Carl Long, General Manager at Witt UK said: “The one time test by BAM helps users of this non-return valve to obtain a permit for their gas supply system. Not only does it enhance the user’s safety by reducing the risk of accidents, it makes savings on costs.”
