It serves as a self-closing stop valve inside a tank trailer, automatically shutting off product flow if the integrated shear section is ruptured in an under-ride accident, or if temperatures exceed 212°F thanks to a fusible plug. The internal air cylinder design saves exterior space and includes a stainless steel jackscrew for manual operation during air system failure. It's typically used on DOT HM183-compliant tank trailers hauling crude oil, gasoline, or chemicals, and features Teflon-encapsulated seals for broad chemical compatibility.
