TECHNICAL DATA FUNCTIONAL DESCRIPTION INFLATABLE SEAT

The sealing system was developed for highly abrasive or very
sensitive media. OPEN CLOSED
UNSEALED
Available for all resilient seated butterfl y valves with
interchangeable seat from DN 80 - DN 600.
In closed position, the liner will be pressed against the disc using
low air pressure.The media is sealed off securely.
Before opening the disc, the chamber is vented behind the liner.
This creates an air gap between the liner and the disc, hence low
torque is required to open the valve.

As the valve rotates into the closed position, the disc makes casual contact with the seat, reducing friction, wear and torque requirements.
ADVANTAGES
Extremely low wear of parts even in contact with abrasive media
CLOSED
PRESSURISED
Low sized actuators due to reduced torques SEALED
Low grinding/-clamping of sensitive media between disc and liner

THE EBRO CONTROL After the valve is closed, the seat infl ates against the disc providing bidirectional bubble tight seal.
1. Signal “OPEN” appears as a digital signal
2. The air pressure is reduced behind the liner
3. The valve will open if there is no pressure on the liner
4. Position “OPEN” will be confi rmed
5. When the signal disappears, the valve will close
6. Position „CLOSED“ will be confi rmed INFLAS ® ECO PRO PRO VACUUM
7. When the valve is closed, the liner will be pressurised Infl atable Seat x x x
8. When pressure is on the liner „OK“ will be reported Infl ation Pressure Control x x x
