Butterfly Valves, Inflatable Seated

The inflatable seated butterfly valves are characterised by less friction, low torque, less wear and longer life. This unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble tight sea, every time. Because the seat makes only casual contact with the disc during valve opening and closing. There is very minimal disc impingement this is in contrast to conventional butterfly valves where disc impingement leads to shaving of the seat, decreasing the overall performance and valve life. Substantially less torque is required to open and close the Posiflate butterfly valve thus a smaller actuator can be used resulting in lower overall valve cost. In actual compassion tests and documented field applications, the Posi-flate butterfly valve outperformed all other valves.
