The S & J 97140 Flame Trap Assembly combines the 97130 thermal operated valve with the 94306 horizontal or vertical flame arrester to effectively inhibit flame propagation in low pressure gas lines. The flame arrester tube bank assembly absorbs heat faster than the ignite gas can produce it. This lowers the gas temperature to below ignition point, thus quenching the flame. The offset design of the horizontal flame arrester prevents condensate from accumulating. The spring loaded thermal valve quickly closes when the fusible link is melted in the presence of fire. This shuts off the flow of gas to prevent catastrophic damage. The fusible element is easily replaced without disassembling the valve. Other valve elements are also easy to replace which simplifies maintenance. Its aluminum and stainless steel components withstand the severest of process environments. The S&J 97140 is especially designed for hydrogen sulfide and hot, wet methane which are the main components of digester gas streams in municipal waste water treatment facilities. The 97140 is 100% U.S. made.
