Application scenarios
Silo Discharge Shut-Off for Highly Abrasive Bulk Solids
Used for pipeline shut-off and process isolation when highly abrasive bulk solids are discharged from a silo or hopper to downstream equipment.
Conveying and Silo Discharge Isolation for Highly Sensitive Bulk Solids
Used for opening, closing, and isolation during the conveying, silo discharge, or process transfer of highly sensitive bulk solids, particularly in applications where material damage must be minimized.

FAQ
What media is the EBRO INFLAS expansion butterfly valve suitable for?
The INFLAS expansion butterfly valve is designed for highly abrasive or highly sensitive media applications. It is suitable for butterfly valve applications that require both media compatibility and sealing performance. Specific media compatibility should be confirmed based on the valve materials, working pressure, and temperature conditions.
What are the nominal size and pressure ranges of the INFLAS expansion butterfly valve?
This series covers a nominal size range of DN80 to DN400, with a standard maximum working pressure of 1 bar. For higher-pressure applications, the actual model and application conditions must be reviewed.
What operating temperature range is supported by the INFLAS expansion butterfly valve?
The operating temperature range of this valve is -40°C to +200°C. The actual permissible temperature depends on the working pressure, conveyed medium, and valve materials. These conditions should be checked together during selection.
Which flange connection standards are supported by the INFLAS expansion butterfly valve?
This valve can be supplied for flange standards EN 1092 PN 6/10/16, ASME Class 150, and AS 4087 PN 16. Flange facings include EN 1092 Form A/B and ASME RF and FF. Before installation, verify the pipeline flange standard, pressure rating, and facing type.
What are the sealing class and actuator connection standards of the INFLAS expansion butterfly valve?
The valve sealing class complies with EN 12266 Leakage rate A and ISO 5208 Category 3. The top flange follows the EN ISO 5211 standard, enabling actuator configuration according to the corresponding interface requirements.
