It is cable-operated, manual (not air-controlled), with a flanged straight outlet and a Buna-N rubber seal disc that provides positive shutoff. The valve is designed with a grooved shear section that meets DOT 178.345-8 and TTMA RP84 requirements, meaning it will break away cleanly if pulled beyond its 10,000-pound force limit. You would replace this valve if the shear section is damaged, the seat fails and leaks, or during tank refurbishment.
