MANUAL LEVER OPERATED CENTRIC DISC BUTTERFLY VALVE LUG TYPE
“aline” Make Manual Lever Operated Centric Disc Butterfly Valve (Lug Type) is a high-performance quarter-turn valve designed for dependable isolation and flow control in industrial piping systems. Featuring a centric disc design with a resilient seat, the valve provides bubble-tight shut-off, low operating torque, and smooth operation for liquids, gases, air, and other compatible media.
The lug type body is manufactured with threaded lugs that allow the valve to be bolted directly between flanges. This design enables dead-end service, making it ideal for applications where one side of the pipeline requires maintenance without shutting down the complete system. Operated by a heavy-duty locking lever, the valve offers quick and easy manual operation with secure positioning.
Manufactured from premium-quality materials such as Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel, and resilient seat materials, the ALINE Lug Type Butterfly Valve delivers outstanding durability, corrosion resistance, and long service life in demanding industrial environments.
The valve is widely used in Water Treatment Plants, Chemical Industries, Pharmaceutical Industries, Food & Beverage Processing, HVAC Systems, Fire Protection Systems, Oil & Gas, Power Plants, Marine Applications, Steel Plants, Cement Industries, Paper Mills, and General Industrial Utilities.
Engineered for reliable sealing, easy installation, and minimal maintenance, the ALINE Manual Lever Operated Lug Type Butterfly Valve ensures consistent and efficient flow control across a wide range of applications.
