The Shand & Jurs Biogas 97141 Flame Trap Assembly combines the 97130 thermal operated valve with the 94309 plate flame arrester to effectively inhibit flame propagation in low pressure gas lines.

The flame arrester quenches the flame front by cooling the flame below its ignition temperature. The flame front enters the arrester and the flame is intercepted by the arrester element which is specifically designed to provide a precision path for the flame to follow. The flame front temperature is reduced to below the ignition point of the protected vapors. This is achieved by dissipating the heat of the flame through the arrester elements and body. The spring loaded thermal valve quickly closes when the fusible link is melted in the presence of flame conditions. 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 Shand & Jurs Biogas 97141 is especially designed for hot, wet methane which is a main component of digester gas streams in municipal waste water treatment facilities.
