The Triad Butterfly valve is the better choice. Many years of research goes into the development of Triad products. Input from plant installations and design engineers drive many of our product features.
For example, the most critical aspect of the Triad butterfly valve is the cartridge seat design. The cartridge seat alleviates problems associated with the dove tail design seats. The cartridge seat contains a unified, rigid component by bonding an elastomer to a hard dense phenolic composite ring, which inserts into the valve body. The phenolic backing keeps the elastomer from shifting during installation, reducing seat tearing and fatigue caused by bunching. In the dovetail design, The overbundance of elastomer exaggerates any swelling. Valve torque is lower and more consistent because the seat dynamics do not rely on being mated between two flanges.
Found below are two visuals which depict exactly how the cartridge seat functions compared to the dovetail seat.
Triad also manufactures high quality high pressure ball valves, metal seated ball valves, flanged ball valves, industrial butterfly valves, high performance butterfly valves, control valves and custom valves to meet your specifications.
