The SVF “Therma-SafeTM” is a rugged and
modular extension device that provides
manual access to valves installed in insulated
piping systems while providing a safe
operating distance for valves used in high
temperature service. The modular design
allows this unit to be fitted directly to the ISO
mounting pad found on SVF ball valves.
