Heavy Duty Butterfly Valve

Posi-flate’s unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for bubble-tight seals.

posi-flate butterfly valvesPosi-flate’s unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for bubble-tight seals. Because the seat makes only casual contact with the disc during valve opening and closing, there is 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 Posi-flate butterfly valve, thus a smaller actuator can be used resulting in lower overall valve cost. Standard valve sizes range from 2 inches (50mm) to 24 inches (600mm) and fit both ANSI and metric flanges. A full line of actuators, limit switches and controls are available to suit individual applications.
