The top flange complies with EN ISO 5211, allowing easy pairing with actuators that feature the corresponding standard interface.
FAQ
What nominal sizes and pressure ranges does the F012-A double flanged butterfly valve cover?
The F012-A covers nominal sizes DN 50 to DN 1400, with a maximum working pressure of 25 bar and a maximum allowable differential pressure of Δp 25 bar. The actually usable pressure range should also be matched to the selected size, connection flange, media, and valve material conditions.
Which flange standards can the F012-A be connected to?
The valve matches flange standards including EN 1092 PN 6/10/16/25, ASME B16.5/B16.47 Class 150 and Class 300, AS/NZS 4087 PN 16/PN21/PN35, AS 2129 Tab.E/Tab.F, and JIS B 2220 10K. ASME Class 150 has a maximum working pressure of 19 bar, and Class 300 has a maximum working pressure of 25 bar; not all flange connections are available for all sizes.
Can the F012-A double flanged butterfly valve be used for single flange installation and different mounting orientations?
Yes. The F012-A features a double flanged design, supports single flange installation, and can be installed in any orientation. Installation should still be confirmed in consideration of the pipeline layout, actuator space, flow direction, and on-site support conditions.
Which sealing standards does the F012-A comply with?
The F012-A meets the EN 12266 Leakage rate A and ISO 5208 Category 3 sealing class requirements, with EN 593 as the operating standard. The valve features a vulcanized seat and single-stem construction with a triple bushing design, making it suitable for high-pressure service.
Can the F012-A be used for vacuum and high- or low-temperature media?
The valve can be used in vacuum service down to 1 mbar absolute pressure, with an operating temperature range of -40°C to +200°C. Temperature suitability is affected by the combination of pressure, media, and materials, and should be confirmed according to the actual model and application conditions.
