Lug type butterfly valve

A Lug Type Butterfly Valve is a quarter-turn rotary motion valve designed for precise flow control in industrial piping systems. Its unique lug-style design features threaded inserts (lugs) on the valve body, allowing it to be bolted between two pipe flanges without nuts. This design ensures easy installation, maintenance, and removal, making it ideal for systems requiring frequent disassembly. Lug-type valves are widely used in water treatment, HVAC, chemical processing, and more.

Performance Features

  1. Robust Construction: Made from durable materials like stainless steel, ductile iron, or carbon steel.

  2. Bidirectional Sealing: Ensures leak-proof performance in both flow directions.

  3. Compact & Lightweight: Saves space and reduces structural load on piping systems.

  4. Low Torque Operation: Smooth disc movement minimizes actuator wear.

  5. Temperature & Pressure Resilience: Handles temperatures from -29°C to 200°C and pressures up to 300 PSI.


Key Advantages

Easy Installation: Lugs enable secure mounting between flanges without disassembling pipes.
Cost-Effective: Lower upfront and maintenance costs compared to gate or globe valves.
Versatility: Compatible with liquids, gases, and semi-solid media (slurries).
Long Service Life: Corrosion-resistant coatings and high-quality elastomers (EPDM, Viton) extend durability.
Low Maintenance: Simple design reduces downtime for repairs.


Applications

Lug-type butterfly valves are ideal for:

  • Water & Wastewater Treatment: Pump stations, pipelines, and filtration systems.

  • HVAC Systems: Heating, cooling, and air-handling units.

  • Oil & Gas: Refineries, fuel transfer lines.

  • Chemical & Pharmaceutical: Acid, alkali, and solvent handling.

  • Food & Beverage: Hygienic processing and CIP (Clean-in-Place) systems.
