Lug Butterfly Valve Manufacturers-Concentric Butterfly Valve with Worm Gear Operator features a disc that rotates around a central axis within the valve body. In a concentric design, the disc is centered both in the flow passage and relative to the valve seat. The concentric design ensures good sealing performance, reducing leakage and providing reliable shut-off. When the worm gear operator is actuated, the worm gear meshes with the worm wheel, converting rotational motion to precisely control the opening and closing of the disc, thereby regulating the flow of fluid through the valve.

100% bi-directional tight shut-off.
Installation without restriction in direction of flow.
Reduced weight and overall dimensions.
Low pressure loss and reduced energy costs.
High Kv / Cv values.
Easy to clean and disinfect for potable water systems etc.
Self cleaning ( no residue will be trapped ).
Good resistance to corrosion.
