It serves as an internal self-closing stop valve on a cargo tank trailer, cutting off product flow in the event of an accident or piping shear. The aluminum body includes a shear section compliant with 49CFR178.345-8, and the internal stainless steel trim with a Teflon-encapsulated main seal ensures compatibility with a wide range of petroleum products and chemicals. You typically replace this valve when it fails to seal completely, shows physical damage, or cannot pass the required leakage and pressure tests during tank trailer inspections.
