Electric cryogenic ball valve CF8

This industrial grade electric cryogenic ball valve is fabricated from high quality CF8 stainless steel and purposefully engineered for liquefied natural gas liquid nitrogen liquid oxygen and liquid carbon dioxide systems It features an extended bonnet design that effectively keeps the stem packing away from extreme cold media to prevent freezing Operational automation is provided by a high torque smart motorized actuator ensuring quick and secure isolation within automated cryogenic storage networks
