GUARANTEED STRENGTH. Composite Fiber is now used in the aerospace and auto industry for strength and weight reduction. We are so confident in the strength of our new BlackMaxx™ Composite Fiber bodied butterfly valve, we guarantee that the body, disc, stem and MaxxLife™ seat will out last and out perform any valve on the market today. No other butterfly valve manufacturer in the world can compete with it.

LIGHTWEIGHT. Combine our BlackMaxx™ Composite Fiber body with our AlloMaxx™ disc and you have the lightest butterfly valve ever made. Just 3.4 lbs on a 5 inch valve. Compare that to 7 to 8 lbs on the competition’s valve- that’s over 50% lighter.

A FOOD GRADE ALTERNATIVE TO STAINLESS STEEL. BlackMaxx™ is available with a Stainless Steel, Ductile, or AlloMaxx™ Ultra-Lightweight Disc. AlloMaxx™ by BTI is the perfect solution for food grade applications. It has all the durability and food safe properties of stainless steel at a fraction of the cost or weight.

ECONOMICAL. Now you don’t have to choose foreign valves to hold cost down. BlackMaxx™ breaks the mold, it’s quality at an inexpensive price, aka American Ingenuity!


Available in 2”, 3” 4”, 5” and 6” sizes.
