Butterfly Valve has inflatable seat.

Press Release Summary:



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 to 30 in.



Original Press Release:


All Stainless Steel Butterfly Valve


Posi-flate has introduced an inflatable seated butterfly valve with a highly polished 316 stainless steel housing and disc. It is suitable for many applications, such as food, chemical and pharmaceutical, and is available in all standard Posi-flate butterfly valve sizes - 2"(50mm) to 30"(750mm).

The inflatable seat design of the Posi-flate butterfly valve provides a better seal by utilizing air pressure to expand the seat against the disc, providing more sealing area and an even pressure distribution against the disc every time. The seat automatically compensates for wear when it inflates against the disc, extending valve life considerably.

Because the Posi-flate disc only makes casual contact with the seat during opening and closing, torque requirements are substantially lower. This ease of movement also allows the disc to come to a perfect 90-degree position every time. Additionally, the smooth profile of the disc helps material flow easier and reduces build-up. For unique fail-safe monitoring, a pressure switch can be utilized to verify a perfect seal.
