Class 600 Triple Offset Butterfly Valve

There are two types of LUG butterfly valves in our market, fully LUG type and semi-LUG type. The semi-LUG is a structure similar to a doule flange end valve, and the fully LUG is a solid construction in the same area. In general, semi-LUG is widely used for large diameter valves, and fully LUG is designed for small butterfly valves.

The sealing performance of the Class 600 Triple Offset Butterfly Valve is the ability of the valve's sealing components to prevent media leakage. This is the most important technical performance indicator of the valve. The valve has three sealing portions: the contact between the opening and closing portion and the two sealing faces of the valve seat; the fit between the packing and the valve stem and the stuffing box; and the connection between the valve body and the cover. Leakage can affect the ability of the valve to cut media. The shutoff valve does not allow internal leakage. Leaks can cause material damage, environmental pollution and serious accidents.
