Product Details

A ‌groove butterfly valve‌ is a type of industrial valve designed for ‌quick installation‌ in piping systems using ‌grooved mechanical couplings‌.
 
Key Advantages:‌
1.‌Rapid Installation‌
      No welding/threading; couplings install in minutes with bolts.
      Ideal for retrofits or confined spaces (e.g., HVAC ducts, fire sprinkler retrofits).
2.‌Modular & Flexible‌
      Easily added/removed for system modifications.
     Compatible with grooved pipes, fittings, and pumps.
3.‌Vibration & Misalignment Tolerance‌
     Groove couplings absorb pipe movement, reducing stress.
 4.‌Cost-Effective‌
     Lower labor/time costs vs. flanged or welded valves.

‌Applications
1.‌Fire Protection Systems‌: Sprinkler lines .
2.‌HVAC‌: Chilled/heating water circuits, air handling units.
3.‌Water/Wastewater‌: Pump stations, treatment plants, irrigation mains.
4.‌Industrial‌: Cooling towers, chemical processing (corrosion-resistant materials).
