Features & Benefits of Butterfly valve double offset - ZEDOX 121 | ARI

  • Double Offset Design: Minimizes friction during operation, which reduces wear and extends valve life. This means smoother opening and closing, even after years of use.
  • High Tightness: Ensures excellent sealing and prevents leaks, maintaining system integrity and reducing maintenance costs.
  • Corrosion Resistance: Constructed from premium materials that resist damage from corrosive fluids, making it suitable for tough industrial settings.
  • Low Operating Torque: Requires less effort for manual or automated operation, enabling quick response and easier handling.
  • Versatile Application: Ideal for use in water treatment, energy plants, chemical processes, and more. Its design adapts to both liquids and gases.
  • Compact and Lightweight: Saves space and simplifies installation in tight locations, reducing downtime during setup or replacement.

The Butterfly valve double offset - ZEDOX 121 | ARI stands out with its smart double offset mechanism. Unlike traditional valves, it ensures the disc moves away from the seal quickly during operation. This unique feature minimizes friction, making each movement smooth and protecting the seal from wear. The result is long-lasting performance and a significant reduction in maintenance needs.

This valve is engineered for stability under pressure, providing dependable shutoff to safeguard your process. Its resilient materials prevent corrosion, meaning you can rely on it even with aggressive fluids or chemicals. The efficient lever or actuator operation delivers low resistance, which cuts down on energy use and operator fatigue.

Install the Butterfly valve double offset - ZEDOX 121 | ARI with confidence in pipelines, tanks, or process lines. Its universal design and standard connections make integration straightforward, so you can focus on your operation instead of complicated assembly.

Choose the Butterfly valve double offset - ZEDOX 121 | ARI for your industrial flow control and experience reliability, efficiency, and peace of mind in every turn.
