97130 Thermal Valve

The S&J 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 255OF, the fusible element melts causing the spring loaded pallet to positively shut off gas flow. Indicator Rod provides notification of valve actuated to the closed position. Fusible element is easily replaceable without disassembling the valve.

The valve can be installed in either a horizontal or vertical position and is good for working pressures up to 5 psig.

The S&J 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. Its aluminum and stainless steel components withstand the severest of process environments.

Standard materials of construction include low copper cast aluminum body, pyrex for the sight glass indicator and aluminum pallet with stainless steel spring and stem.

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