The Shand & Jurs Biogas 97140 Flame Trap Assembly combines the 97130 thermal operated valve with the 94306 vertical or the 94307 horizontal flame arrester, to effectively inhibit flame propagation in low pressure gas lines.

The flame arrester tube bank assembly absorbs heat faster than the ignited 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, rated at 255°F, melts. This shuts off the flow of gas to prevent the propagation of the ignited gas.

The fusible element is easily replaced without disassembling the valve. Other valve elements are also easy to replace which simplifies maintenance.

An optional proximity switch is available that can be mounted to the visual indicator and will send a signal once the pallet has closed.

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.
