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.

Salient Features

• 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

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. Aquaseals 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.

Salient Features :

• 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

L&T Valves Limited manufactures a comprehensive range of Double Block & Bleed Plug Valves in sizes up to 30 (750 mm) and in ASME classes 150 and 300. The valves are offered in combinations of size, pressure class, material, end-connection, etc to suit customer requirements.

Double Block & Bleed Plug Valve provides online-verifiable high-integrity positive shut-off, and is a safe and reliable replacement for the old two-valve system. Globally, the valve has emerged as the industry standard for movement and storage of petroleum products in refineries, tank farms and terminals.

L&T Double Block & Bleed Plug Valve is designed in accordance with key international standards. It also meets the requirements of major oil & gas industry standards and customer specifications

Salient features :

• Double Block & Bleed Valve.
• Mechanically-assisted sealing - Reliable bubble-tight shut-off at low and high pressures.
• Cavity Pressure Relief System (provided to relieve the built up cavity pressure).
• Non-lubricated - Sealant not required to achieve zero leakage.
• Unique valve operation mechanism - Segments do not rub against seats during plug rotation
• Cavity Relief System - Prevents body cavity pressure build-up. Pressure relieved to upstream or downstream based on customer requirement.
• On-line maintenance - Segments can be replaced on line.
• Fire-Safe
• Drain provided for online verification / draining the cavity.
