The S&J Biogas 97130 Thermal Valve is a thermally operated shut-off
valve typically located in low pressure biogas lines such as downstream of anaerobic
digesters, landfills and lagoons, or upstream of flares and waste gas burners.
Its normal
operating position is open until the melting point of the fusible element is exceeded.
When the line temperature reaches 255° F, which is usually in the presence of fires and
flame propagation, the fusible element melts causing the spring loaded pallet to
positively shut off gas flow and prevent the fire from continuing. Indicator Rod
provides notification of valve actuated to the closed position. Fusible element is
easily replaceable without disassembling the valve.
This unit can be used alone, but
its most common application is as a component in item number 97140/97141, Flame Trap
Assembly.
Its aluminum and stainless steel components withstand the severest of
process environments. The S&J Biogas 97130 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.
Standard materials of construction include an
aluminum body with stainless steel pallet and spring.
The 97130 is 100% U.S. made.
