Full lug butterfly valve has a flanged body, or lug-to-lug body, in which full lugs are threaded at each end to connect with neighboring flange screws. There are usually two forms on the lugs of lug type butterfly valves, one is through-hole (customarily called A type in China), and the other is through-hole with internal threads (called LT type in China). These two designs are respectively suitable for different installation scenarios, providing more installation options.
