Butterfly Valve has inflatable seat.

Butterfly valve has polished 316 stainless-steel housing and disc. Air pressure expands seat against disc, providing even pressure distribution. Inflatable-seat automatically compensates for wear, extending valve life, and allows disc to come to 90 deg position. Smooth disc profile reduces build-up of material. Suitable for chemical and pharmaceutical applications, it is available in sizes from 2...
