L&T Valves offers a versatile range of PTFE Sleeved Plug Valves. The valves offer tight shutoff without sealants or lubricants and are available in sizes up to 400 mm, in ASME classes 150 and 300.

The interference fit of the taper plug with PTFE sleeve creates a bubble-tight seal. The sleeve totally surrounds the plug, and sealing occurs around the circumference of the plug. The integrity of the seal is totally independent of line pressure.

The rugged construction, reliable bubble-tight sealing and on-line maintenance feature make the valve an ideal choice for chemicals and highly aggressive process media.

Aquaseal Max is a fabricated steel butterfly valve developed as an 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.

The key feature of Aquaseal Max Fabricated Steel Butterfly Valve is a Self-energising Disc Seal that uses line pressure to provide assured sealing.

Salient Features:

Self-energising Disc Seal - Bi-directional bubble-tight sealing

Assured Sealing to Atmosphere

Lighter and Stronger Construction

Lower Torque, Longer Life

Maintenance-free Bearings
