Premium Lug Concentric Butterfly Valve by CTGV
A Lug Concentric Butterfly Valve is a quarter-turn rotary valve featuring threaded or bolt-hole lugs cast integrally with the valve body, enabling direct pipeline connection without requiring full flange bolting. This design combines the compactness of wafer valves with the installation flexibility of flanged valves.
1.The structure is simple and compact, lighter weight, ease of assembly and disassembly and repair.
2.The operating torque is small, to turn 90 ° hoist light quickly. ;
3.Small flow resistance, flow characteristics approximate inclined straight line, energy-saving effect.
4.Reliable sealing, leakage is zero, and long service life.
5.Can be made of various materials suitable for various media.
