Kockums diverters using Posiflate valves
HOW IT WORKS
Closed, unsealed
As the valve rotates into the closed position, the disc makes only casual contact with the seat, reducing friction, wear and torque requirements.
Closed, sealed
After the valve is closed, the seat inflates against the disc providing more sealing surface and an even pressure distribution against the disc.
Open, unsealed
Before the valve opens, the Seat is first deflated. The disc is then free to rotate to the open position.

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.
