Lever-handle butterfly valves in this series are engineered with a reinforced body and specially designed seat to deliver dependable quarter-turn isolation and throttling performance across general industrial and water-handling applications.
Key features:
• A specially designed valve seat improves sealing performance compared with standard butterfly valve seat geometries, reducing leakage across the closed position.
• A thickened valve body with reinforcing ribs and no hollow sections is engineered to minimize stress concentration, enhancing structural strength under harsh operating conditions such as pressure surges, vibration, and mechanical loading.
• A spherical-profile disc design improves durability at the seat interface while also improving the valve's Cv (flow coefficient), reducing pressure drop across the valve compared with flatter disc profiles.
• The lever handle provides quick, tactile quarter-turn operation with position indication, suiting frequent on/off duty as well as basic throttling.
The combination of the reinforced body structure and optimized disc geometry allows the valve to maintain sealing integrity and structural reliability over repeated cycling, which is particularly relevant for larger diameter lines where body stress and disc loading are greater.
Typical applications include water treatment plants, HVAC systems, general chemical process lines, and industrial piping where a lightweight, corrosion-resistant, quarter-turn valve is preferred over heavier metal alternatives. The lever handle configuration is well suited to smaller and mid-range diameters where manual quarter-turn operation remains practical without a gear operator.
