L&T 2 Piece Ball Valve

The L&T 2-Piece Ball Valve is a robust, versatile industrial valve designed for moderate-to-high pressure applications across chemical, power, oil & gas, and utility sectors. Featuring a split-body construction (body and tailpiece), it provides a full flow area with minimal pressure drop, making it a superior choice for viscous fluids, slurries, and high-flow pipelines.

Technical Specifications

• Design Type: 2-Piece Split Body (Full Bore / Full Port Design)
• End Connections: Flanged End (ANSI Class 150 / 300 / 600), Screwed (BSP/NPT), Socket Weld, or Butt Weld
• Body Material: ASTM A216 Gr. WCB (Cast Carbon Steel), ASTM A105 (Forged CS), ASTM A351 Gr. CF8/CF8M (Cast SS304/SS316)
• Ball & Stem Trim: CF8M (SS316) or CF8 (SS304) floating ball with SS316 / SS410 blowout-proof stem
• Seat & Seal Rings: Virgin PTFE, Reinforced PTFE (RPTFE), or PEEK (for elevated temperatures)
• Size Range: 15 mm to 300 mm (1/2" to 12" NB)
• Pressure Rating: ASME Class 150, Class 300, and Class 600
• Temperature Threshold: -29°C to +220°C (up to +260°C with modified seating)
• Design & Fire Standards: BS EN ISO 17292 / API 6D, Fire Safe as per API 607 / ISO 10497

Key Features & Operational Benefits

• Full Bore Flow Profile: The internal diameter matches the pipe diameter, eliminating flow restriction, turbulence, and pressure drop.
• Fire-Safe & Anti-Static Design: Built-in grounding springs ensure continuous electrical continuity, while secondary metal-to-metal seating prevents leakage if soft seats burn during a fire.
• Blowout-Proof Bottom-Entry Stem: Features an internal collar design that prevents stem blowout under high line pressure.
• In-Line Maintainability: The two-piece split-body design allows easy disassembly and seal replacement during scheduled overhauls.
• ISO 5211 Direct Mounting Pad: Enables hassle-free automation with pneumatic or electric actuators without extra brackets.

Primary Industrial Applications

• Oil & Gas / Petrochemicals: Hydrocarbon lines, fuel gas distribution, and tank farm isolation.
• Chemical & Refining: Process fluid handling, solvent transfer, and aggressive acid lines.
• Power & Thermal Utilities: Cooling water systems, medium-pressure steam, and boiler feed lines.
• Water & Sewage: Desalination plants, industrial water treatment, and high-volume water pumping lines.
