Posi-Flate Butterfly Valves

Posi-Flate Inflatable Seated Butterfly Valves Other Valves Fight Friction. We Designed It Out! Unlike other valves that seal with friction, Posi-Flate's unique butterfly valve uses an inflatable seat to seal with air pressure. Thus it requires less torque and a smaller actuator, resulting in lower overall valve cost. Plus, the seat automatically compensates for wear, providing longer valve life.
