FUSIBLE LINK AUTOMATIC SHUT-OFF VALVES
The DSS fusible link shut-off valve is ideal for fuel farms and other pipelines that carry flammable media in and around airports. With OSHA and many insurance companies now requiring automatic shut-off of valves in case of fire, fusible link fire safe valves have become common throughout the industry. Fire safe fusible link valve assemblies (also referred to as thermal shut-off valves) are designed for flow shutoff protection in piping systems handling flammable gasses or liquids, solvents, toxic fluids, or any other potentially dangerous media. (Click here for an overview of fusible link assembly applications.) These fire control valves terminate flow of flammable liquids in the event of fire, aiding in reducing fire intensity. In the event of fire, the fusible link separates, allowing the top mounted spring pack to drive an API 607 fire safe rated valve into a closed position. Our unique design eliminates the need for two thermal control shut-off valves in the line since one fire safe valve can be manually operated even while the fire control fail safe unit is armed. In addition, our newest innovation is an electro-thermal link that can be automatically tripped through a low voltage electric signal.We have four different styles to choose from depending on valve torque and application.
