L&T Single Piece Ball Valve

The L&T Single-Piece Ball Valve (1-Piece Monoblock Design) is an economical, compact, and high-integrity fluid control valve designed for general utility, water, oil, gas (WOG), and low-to-medium pressure industrial processes. Featuring a single-body construction, this valve minimizes potential body leakage paths, making it a reliable and leak-proof solution for space-constrained piping networks.

Technical Specifications

• Design Type: 1-Piece Solid Body / Monoblock (Reduced Bore / Regular Port)
• End Connections: Screwed End (BSP / NPT Threads), Socket Weld, or Flanged (Class 150)
• Body Material: ASTM A105 Forged Carbon Steel, ASTM A216 Gr. WCB Cast Steel, or Stainless Steel (CF8 / CF8M / SS304 / SS316)
• Internal Trim: SS304 / SS316 Solid Ball with Anti-Blowout Stem
• Seat & Seals: Virgin PTFE / RPTFE for bubble-tight shut-off
• Size Range: 15 mm to 50 mm (1/2" to 2" NB)
• Pressure Class: Class 150, Class 300, or 1000 WOG (Up to 69 bar / 1000 PSI)
• Temperature Range: -20°C to +180°C (depending on seat material)
• Standards: BS EN ISO 17292 / ASME B16.34, Tested as per API 598

Key Features & Advantages

• Minimized Joint Leakage: The one-piece body design eliminates body-joint flanged/screwed connections, drastically reducing potential external leakage points.
• Compact & Lightweight: Ideal for compact skids, OEM equipment, and tight installation spaces where weight and size restrictions apply.
• Blowout-Proof Stem: Internal bottom-entry stem collar prevents stem ejection under system pressure surges.
• Low Operating Torque: Precision-machined ball and smooth PTFE seating ensure effortless manual lever operation and reduced wear.
• Cost-Effective Reliability: Offers high durability and tight shut-off at a lower cost compared to multi-piece valve assemblies.

Primary Applications

• Utility Lines: Compressed air systems, industrial water lines, cooling water loops, and inert gas distribution.
• Chemical & Process Lines: Low-pressure chemical feed, solvent handling, and fuel oil transfer.
• HVAC & OEM Skids: Chilled water systems, boiler feed accessories, and pump skids.
