Already Better, the Best Got Bigger

8" Composite Fiber Butterfly Valve

Guaranteed Strength

Composite Fiber is now used in the aerospace and auto industry for both strength and weight reduction. Confident of the strength, Bulk Tank guarantees that the body, disc, stem and MaxxLife™ Seat* on their BlackMaxx™ Composite Fiber bodied butterfly valve will outlast and out perform any valve on the market today. No other butterfly valve manufacturer in the world can compete with it.

(*MaxxLife™ Seats are not suitable for fuel/petroleum service)

Combine B.T.I.'s BlackMaxx™ Composite Fiber body with their AlloMaxx™ Ultra-Lightweight Disc and you have the lightest butterfly valve ever made weighing in at only 3.4 lbs. on a 5-inch valve, which is over 50% lighter than the competition's valve that weighs 7-8 lbs.

Food Grade Alternative to Stainless Steel

BlackMaxx™ is available in three different types of discs - Stainless Steel, Ductile and AlloMaxx™ Ultra-Lightweight. AlloMaxx™ is the perfect solution for food grade applications having all of the durability and food safe properties of stainless steel at a fraction of the cost or weight.


Now you no longer have to choose foreign valves to try and keep the costs of operation down. B.T.I.'s BlackMaxx™ line of Composite Fiber Butterfly Valves does that for you - combining quality at an inexpensive price - and 100% American made.
