Posi-flate manufactures a complete line of inflatable seated butterfly valves, double dump valves, and gravity diverter valves in a variety of materials of construction, including stainless steel for sanitary applications. The company also manufactures vibratory gate valves and linear vibrators, and offers an extensive line of valve operators and accessories, including actuators and limit switches.
Posi-flate's unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble-tight seal, every time. Because the seat makes only casual contact with the disc during valve opening and closing, there is minimal disc impingement.
