The MaxiSeal Butterfly Valve is a result of AVM’s expertise in cutting-edge valve technology, starting more than 5 decades ago. MaxiSeal was designed for the water industry, taking into account the best available double offset technology, exceeding the requirements of EN593 and AWWA C504.

The MaxiSeal Butterfly Valves are used in thousands of installations worldwide, and is a proven design. Over the years, the valve has undergone constant refinement and perfection, and therefore incorporates unique features and benefits.

The shaft is secured to the disc by pins. The pins are secured by set-screws. The disc hubs are enclosed.
O-rings on the bearings and the covers provide perfect sealing for open and blind ends.
