L&T AQUA SEAL BUTTERFLY VALVE PN10
An L&T Aquaseal Butterfly Valve PN10 delivers zero-leakage fluid isolation and flow regulation across commercial, municipal, and industrial piping networks. Designed and manufactured by L&T Valves, this elastomer-lined wafer butterfly valve uses an integrally molded vulcanized body liner—a seat vulcanized in-situ onto the cast iron body—to eliminate seat movement, lower operational torque, and extend service life compared to loose-liner alternatives.

Material Options & Configurations
- Disc Material Choices: Ductile Iron (SG Iron) with optional protective epoxy/nylon coating, or corrosion-resistant Stainless Steel (SS 316 / SS 410) for harsh fluids.
- Elastomer Seat Options: Nitrile (NBR) for oils, ambient water, and compressed air; EPDM for HVAC, hot water, and mild chemicals.
- Actuation Methods: Manual Hand-Lever operation (DN50 to DN200); heavy-duty Worm Gearbox (DN200 to DN600). Pneumatic and electric actuation options are available via standard ISO 5211 mounting pads.
Standard Catalog Variants
- Cat No. IBFLPC PN10: Features a Cast Iron body, SG Iron disc, Nitrile rubber liner, and manual lever actuation. Ideal for general water supply and HVAC loops.
- Cat No. IBF3SC PN10: Built with a Cast Iron body, Stainless Steel (SS 316) disc, and Nitrile body liner with lever control. Recommended for treated water, mild chemicals, and abrasive fluids requiring enhanced corrosion protection.
Primary Industrial Applications
- Water supply systems and municipal drinking water distribution
- Industrial HVAC cooling tower loops and chilled water circuits
- Firefighting mains and utility washdown networks
- Agricultural irrigation pipelines and wastewater pre-treatment units
Does your project require specific flange sizing (ANSI Class 120/150 vs. BS10 Table E) or automated actuator sizing for this PN10 valve line?
