Pneumatic inflatable butterfly valve with unique design use air pressure to expand the seat against the disc that providing evenly distributed pressure for the sealing. With less torque to open and close, thus can mount a smaller actuator to save operating space and valve cost.
Inflatable butterfly valve have less friction, low torque and wear resistance, thus very suitable for dry powder solid, particle, abrasive, gas, slurry and so on, is the preferred product for pneumatic conveying system equipment.
