Inflatable Seated Concentric Butterfly Valve for Industrial Use with Inchangeable Seat

Product Description

Product Description
Series A31INF inflatable seated butterfly valves use air pressure to expand the seat against the disc, providing even pressure distribution for a bubble-tight seal in every close. Because the seat has no contact with the disc during valve opening and closing, there is minimum disc to seat friction.
In actual comparison tests and documented field applications, an A31INF butterfly valve lives more than one million cycles. For dry solids, gases, slurry and high abrasion applications, the A31 inflatable seated butterfly valve is unsurpassed.
