L&T Valves

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.

Salient Features:

• Taper Plug Design - Lower operating torque compared to lubricated plug valves
• Plug Adjustment Option - Enables online maintenance
• Avoids downtime
• Large PTFE Sleeve - Bubble-tight shutoff
• No metal-to-metal contact
• Longer service life
• Positively-locked Sleeve - Reliable sealing through thermal cycles
• Wiping action between sleeve and plug - Durability in slurry lines
• Reverse-lip PFA Diaphragm - Self-adjusting dynamic stem seal provides assured sealing to atmosphere
• Rugged Body - Long and reliable service life
• No Cavities - Line Fluid does not get entrapped

Tilting Disc Check Valve

• The disc has a pivot axis closer to the flow-bore centre-line compared with Swing Check Valves.
• Disc seats against a conical surface on the seat ring
• Suitable for pulsating flow and fluid with particulates
• Low susceptibility to water hammer

Axial Flow Check Valve

• Flow forces the disc open against spring force; when the flow is reversed, the spring quickly close the valve by forcing the disc against a seat
• Axial Flow Check Valve offers lower pressure drop, lower reverse flows and low slamming
