This butterfly valve has an
inflatable seat for tight closure


The Posi-flate butterfly valve (photo) has a highly polished Type 316 stainless-steel housing and disk. Its surface finish helps to reduce buildup, making it appropriate for


many applications in the chemical, food and pharmaceutical sectors. It is available in sizes from 2–20 in. The inflatable seat design provides a better seal by using air pressure to expand the seat against the disk, providing more sealing area and an even pressure distribution against the disk. Because the disk only makes casual contact with the seat during opening and closing, torque requirements are said to be substantially lower. Its ease of movement allows the disk to come to a perfect 90-deg position every time, says the company. — Posiflate, St. Paul, Minn.
