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.
