L&T STAINLESS STEEL VALVES
Stainless Steel Valves by L&T: Engineered for Corrosive and Cryogenic Service
L&T Valves stands as a global leader in the manufacturing of Gate, Globe, and Check valves, delivering reliable flow control solutions across critical applications. Known for its engineering excellence, L&T offers a specialized range of corrosion-resistant and cryogenic stainless steel valves built to withstand the most demanding environments in chemical, petrochemical, and fertilizer industries.
L&T Corrosion-Resistant Stainless Steel Valves (API 603 – ASME B16.34)
Leveraging decades of expertise, we provide stainless steel gate, globe, and check valves in sizes ranging from 2″ to 24″ (50 mm to 600 mm), and ASME pressure classes from 150 to 600. These valves are crafted using various grades of austenitic stainless steels, delivering long-term performance in corrosive media.
Gate Valves - Bolted Bonnet
L&T’s corrosion-resistant gate valves feature:
- Integral body seats with optional in-situ hard-facing (Trim 12 and 16).
- Flex wedge design to accommodate seat distortion and prevent disc jamming.
- One-piece forged stems with T-heads for enhanced strength.
- API 624 and ISO 15848 compliance for fugitive emissions.
- Compact body-bonnet joints—square for 2", oval for 3", and circular for other sizes and classes.
Globe Valves - Bolted Bonnet
Designed for controlled flow, these globe valves offer:
- Integral body seat with optional hard-facing.
- Non-rotating rising stem for lower operating torque.
- Swivel disc connection for optimal sealing.
- Guided disc to minimize vibration during throttling.
- Emissions compliance as per API 624 and ISO 15848.
Check Valves - Bolted Bonnet
For backflow prevention, L&T check valves deliver:
- Internally housed hinge to eliminate leakage paths.
- Integral seats with optional hard-facing (Trim 12 and 16).
- Custom joint shapes depending on valve size for consistent performance.
L&T Cryogenic Stainless Steel Valves
L&T also offers a full range of cryogenic gate, globe, and check valves for service down to –196°C. Sizes go up to 54″ and pressure classes extend to ASME 2500. These valves comply with BS 6364 and ISO 28921, making them ideal for LNG and other cryogenic operations. Key features include:
- Extended bonnets to keep packing above cryogenic temperatures.
- Thermal stabilization to maintain dimensional integrity.
- Hard-faced seating surfaces to prevent galling.
- Cavity pressure relief to eliminate thermal pressure build-up.
Traceability and Versatility of L&T Stainless Steel Valves
All L&T stainless steel valves can be equipped with ValvTrac™ RFID tagging for full traceability throughout their lifecycle. Moreover, valves are available in a wide selection of metallurgies tailored to suit various low-temperature and corrosive service conditions.
