Beyond Metal: How the New 565 Butterfly Valve is Redefining Piping Efficiency

By Alex Gross

GF is raising the standard for innovative polymer solutions with the launch of the 565 Butterfly Valve, the latest addition to the Uponor ChlorFIT® Schedule 80 Corzan® CPVC system. This solution utilizes a lighter, more sustainable design compared to metals to improve overall installation efficiency while upholding the lasting quality that defines the Uponor brand.

Beyond its sustainable design and lasting quality, the 565 Butterfly Valve offers the versatility required for complex installation environments. It enables peak efficiency across domestic water, hydronic heating, chilled water, and industrial water applications. Additionally, it comes in a variety of configurations, including wafer and lug designs, which easily integrate into new or retrofit systems. The valve's adaptability allows users to optimize performance in every segment of a water management system.


The 565 Butterfly Valve offering provides several advantages over traditional metals, including:
 
  • Up to 60% lighter in weight, enabling faster, safer, and more efficient installations
  • Corrosion and chemical-resistant materials for long-term durability in aggressive environments
  • Low operating torque with optimized disc and bushing design to provide effortless actuation, increasing valve service life
  • Peroxide-cured EPDM seals for greater reliability and longevity compared to sulfur-cured alternatives
  • Global compatibility, meeting ISO, DIN, and ANSI standards for new, retrofit, and service applications
Available in 2" to 12" sizes for Gear Wafer and Gear Lug as well as 2" to 8" for Lever Wafer and Lever Lug, the comprehensive offering delivers a superior flow-control solution that underscores GF's commitment to an integrated systems approach.
