L & T Valves

Triple-offset Butterfly Valves

  • Triple-offset Geometry
  • Special Disc Profile
  • Laminar Resilient Disc Seal
  • Raised conical Body Seat
  • Fire-safe design
  • One-piece blowout-proof Shaft
  • High integrity Shaft Sealing

L&T Valves manufactures a comprehensive range of Triple-offset Butterfly Valves in a variety of body styles and end-connections to address critical services.

The unique triple-offset geometry ensures that the disc seat and body seat are in contact only at the final shutoff position, thereby eliminating wear and enhancing service life.

The valves are available in ASME classes from 150 to 600 in sizes up to 80 inches in a variety of materials.

Butterfly Valves – Integrally-moulded

  • Longer Life
  • Tight Sealing, and Consistent Low Torque
  • Assured Shaft Sealing
  • Lower Resistance to Flow – Disc design
  • Ease of Installation
  • One-piece blowout-proof Shaft
  • Reliable Drive

Aquaseal Integrally-moulded Butterfly Valve is available in various sizes from in PN 10 pressure rating.

The valve was developed to provide reliable sealing in water and air lines, and is today the industry benchmark.

The most striking feature of Aquaseal Butterfly Valve is its integrally-moulded body liner. Aquaseal’s elastomer body seat is vulcanised insitu onto the body using high temperature and pressure, and this provides longer life and superior performance when compared to valves with loose liners.

Aquaseal requires no maintenance, and is truly a fit-and-forget valve.

Fabricated Steel

  • Self-energising Disc Seal
  • Lighter and Stronger Construction
  • Assured Sealing to Atmosphere
  • Lower Torque, Longer Life
  • Maintenance-free Bearings

Aquaseal Max is a fabricated steel butterfly valve developed as an ideal alternate for cast iron butterfly and sluice valves in water distribution systems. The highly reliable valve also finds application in power plants, utility and fire water lines, and HVAC systems. Customised Aquaseal Max can be used to handle air, gases and vacuum services. The valve has successfully under gone Proof of Design (POD) test as per AWWA C 504 and AWWA C 516.

Process Ball Valves


  • Mirror-finished solid ball.
  • Fine-grained PTFE seats.
  • Fire-safe.
  • Cavity Pressure Relief mechanism.
  • Blowout-proof stem.
  • Leak-tight stem sealing.
  • Antistatic feature.

L&T Valves manufactures a wide range of soft-seated Process Ball Valves.

The valves are of floating-ball design where the ball moves towards the downstream seat, under pressure, to effect a tight seal.

The valves are available in sizes up to 12 inches and ASME classes up to 600.The valves are available in three-piece, two-piece and single-piece construction, in full-bore and reduced bore in a variety of materials.

Gate, Globe & Check Valves


  • Body and Bonnet – Cast with uniform sections, precision machined.
  • Body: Permits full swing of disc on downstream side – Lower flow resistance and disc erosion.
  • Disc: Internally-hinged – No opening on the body, higher integrity.
  • Disc secured to hinge using lock nut and pin.
  • Disc free to rotate to avoid localized wear.

L&T Valves manufactures a wide variety of Gate, Globe & Check Valves in bolted-bonnet design.

The valves are approved by the global majors in oil & gas and power and have a reputation for reliable performance in critical services, across the globe.

Valves in bolted bonnet construction are available in pressure classes from 150 to 2500, in a variety of materials and end-connections.
