Overview
Sigma fusible plugs are commonly referred to as temperature safety elements (TSE) in the safety system industry. All fusible plugs are equipped with a built-in fusible alloy core, which will melt under the action of fire or high temperature heat sources. Before reaching the melting temperature, the fusible plug can maintain the working pressure of the control circuit; Once the low melting point melting alloy melts, the ESD control circuit will lose pressure, triggering an emergency shutdown procedure or closing the safety valve. The $r $n fusible plug is the core component in the vast majority of pneumatic ESD control circuits. The $r $n fusible element is made of low melting point eutectic alloy, and the valve body is made of 316 stainless steel, which is heat-resistant and fire safe.
