Lug butterfly valve

Lug butterfly valves are compact quarter-turn valves bolted to the pipeline on both sides through multiple bolting points. Thanks to the threaded lugs on the body, one side of the pipeline can be dismantled for maintenance without removing the valve.

Advantages

  • Easy maintenance: only one side of the pipeline needs to be dismantled
  • High mechanical strength: a stronger, more rigid flange joint
  • Low leakage risk: reliable disc-to-seat alignment
  • Dead-end service: the downstream line can be isolated while the system is running
  • Available in a wide range of sizes

Applications

  • Water distribution and treatment systems
  • HVAC (heating, ventilation, air conditioning)
  • Chemical and petrochemical process lines
  • Fire-fighting systems
  • Power plants
  • Marine and ship machinery
  • Food and beverage production
