L&T Valves manufactures a wide range of butterfly control valves for the power and hydrocarbon industries.The valves are designed using state-of-the-art 3D design, simulation and analysis software. Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are used to fine-tune product performance. Rigorous prototype tests – both in-house and at advanced flow-control research establishments – ensure that the customised solutions meet customer expectations.
Butterfly Control Valves, ideal for high flow-rate applications, are available in ASME classes 150 and 300, in sizes up to 24” (600 mm). Butterfly Control Valves are built on the SIL-3 capable Triple-offset Butterfly Valves that provide bidirectional bubble-tight sealing. The control valve offers flow characteristics close to linear making it ideal for both control and on-off services.
