Triple Eccentric Structure

AM780 High Performance Triple Eccentric Butterfly Valve

The advance metal seating high performance triple eccentric butterfly valve provides a bi-directional bubble tight shut off. This is achieved by introducing state-of-the-art triple eccentric disc geometry. The valve shaft is off-set against the seal, (1st off-set), and against center line of the valve (2ndt off-set). The seating edges are machined with a continuously changing slope from an angle alpha on top of the oval seat ring to an angle beta at the opposite side (3rd off-set angular).

This geometry ensures that the seat ring stays clear of the seat except at the final shut-off position, resulting in long seat life and operating cycles in excess of 500 000.

This range of valve is particular for the triple eccentric design, the lamellar seal ring which is mounted on the disc and is made of stainless steel metal rings including sealing material as graphite. The triple eccentric design allows the disc a translation movement to permit the contact between the lamellar seal ring and the seat on the body of the valve only at shut-off.
