Double Offset, Heavy Duty Design Highly Efficient, Soft Sealing 

The Double Eccentric Butterfly Valve is the result of AVM’s expertise in cutting-edge valve technology, starting more than 5 decadesDouble Eccentric Butterfly Valve – AVM ago.

Our Butterfly Valve was designed for the water industry, taking into account the best available double  offset technology, exceeding the requirements of EN 593 and AWWA C504.

A wide selection of materials is available; also internal hard rubber lining for saline applications.

Sizes and pressures go up to DN 3000 and PN 40 as standard (larger is possible).

Quality, self-locking worm gear actuators are included, with a wide choice of operational options.

Disc seal replacement in the field is easy, without removal of the valve from the line.

Powder epoxy with drinking water certificate is always applied.

Quality is of utmost concern: Materials with highest integrity, advanced production technology,

first-class testing facilities and strict quality control ensure years of trouble free performance.

The AVM Butterfly Valve should be your first choice.
