Stainless Steel Lug Type Butterfly Valve Graphics

Stainless Steel Lug Type Butterfly Valve

A Stainless Steel Lug Type Butterfly Valve is a quarter-turn valve designed with threaded inserts (lugs) around the body, allowing it to be bolted directly between flanges in a pipeline. This design enables easy installation and removal of the valve from one side of the piping system without disturbing the opposite side, making it ideal for systems requiring frequent maintenance. Built from premium stainless steels such as SS304, SS316, or SS316L, the lug type butterfly valve offers excellent corrosion resistance, strength, and reliability in high-performance flow control applications across industries such as chemical processing, water treatment, oil & gas, marine, and HVAC systems.

Key Features of Stainless Steel Lug Type Butterfly Valve

  • Lug-Type Design: Threaded inserts allow independent pipeline disassembly on either side.
  • Quarter-Turn Operation: Quick and efficient shut-off or throttling capability.
  • Durable Stainless Steel Body & Disc: High resistance to corrosion, erosion, and wear.
  • Tight Shut-Off: Resilient or metal seat options ensure zero-leakage performance.
  • Maintenance Friendly: Valve can be serviced or replaced without disturbing the full pipeline.
  • Automation Compatible: Can be equipped with pneumatic, electric, or hydraulic actuators.
  • Wide Range of Applications: Suitable for liquids, gases, steam, and semi-solids.
  • Standard Compliance: Meets international standards such as API, ASME, and ISO.
