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.

1. ASME classes from 150 and 300

2. Sizes up to 24" (600 mm)

L&T Butterfly Control Valves are offered in a variety of body styles, materials and actuation options to meet customer requirements.

1. Pneumatic

2. Hydraulic

3. Electrical

1. Bidirectional bubble-tight sealing

2. Triple-offset geometry - low wear-and-tear, low torque

3. Metal-to-metal seats

4. Longer service life

5. Anti-blowout shaft

6. Suitable for temperatures up to 538�C (1000�F)

7. Meets ISO 15848-1 Class A Fugitive Emission & NACE: MR0175 requirements

8. Can be offered with Valve Diagnostic Software to monitor and enhance valve/ process performance

1. Design - API 609 (Category B)

2. Pressure Temperature Rating - ASME B16.34

3. Leakage Class - ANSI/ FCI 70-2

4. Systematic Integrity (SIL) - IEC 61508

L&T Valves manufactures a comprehensive range of Double Block & Bleed (DBB) Plug Valves in sizes up to 30" (750 mm), and in ASME classes from 150 to 600. The valves are offered in a combination of materials and actuation options to suit customer requirements. The highly reliable valve has successfully completed over 10,000 cycles at its rated pressure.

Double Block & Bleed Plug Valve provides online-verifiable bubble tight sealing and is a safe and reliable replacement to the conventional two-valve system. In this valve, high integrity positive shut-off is obtained mechanically, independent of line pressure, without sealants/ lubricants. Globally, the valve has emerged as the industry standard for movement and storage of petroleum products in refineries, petrochemical plants pipelines, tank farms and terminals.

1. Antistatic Test

2. Drive-train Strength Test

3. Endurance Test

4. Fire Test

5. Fugitive Emission Test

6. Torque Test

The quality management system has been certified to comply with

1. ISO 9001: 2008

2. API Spec Q1

Established processes control all stages of manufacture to ensure quality consistent with international standards and customer requirements. A world-class manufacturing and QA infrastructure guarantees that each DBB Plug Valve delivers reliable performance. Dimensional accuracy and consistency are obtained using CNC and Special Purpose Machines. International health, safety and environment standards govern every phase of the manufacturing process. The plants are zero discharge units and are pioneers in green initiatives.

DBB Plug Valves are designed in accordance with key international standards. They also meet the requirements of major hydrocarbon industry standards and customer specifications.
