Tired of premature wear on your butterfly valves? Try POSI-FLATE Inflatable Seated Butterfly Valves today!
How it works:
1. 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.
2. 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.
3. Open & Unsealed – Before the valve opens, the seat is first deflated. The disc is then free to rotate to the open position.
Not having a direct interface between valve and seal on your butterfly valve can drastically improve the lifetime on your valves.
