FAQ
What are the applicable diameters, pressure, and temperature ranges of the F012-K1 and F012-WN double flange butterfly valves?
The series covers nominal diameters DN 150 to DN 2000, with larger diameters subject to confirmation based on actual requirements; the standard working pressure is 16 bar. The working temperature range is -40°C to +200°C, but the final allowable operating conditions depend on pressure, medium, and valve materials, and should be verified against the actual model and application conditions.
Which pipeline flange standards and sealing face types can this double flange butterfly valve match?
The valve matches EN 1092 PN 6, PN 10, and PN 16, ASME Class 150, and AS/NZS 4087 PN 16 connection flanges; the flange sealing faces are suitable for EN 1092 Form A/B as well as ASME RF and FF. Special flange standards should be confirmed against actual project requirements.
Can the F012-K1 F012-WN be used in pipelines requiring bidirectional sealing?
Yes. The series features a full bidirectional sealing design with a sealing class compliant with EN 12266 Leakage Rate A and ISO 5208 Category 3, suitable for butterfly valve installations requiring bidirectional leakage control.
When installing the F012-K1 F012-WN, is it necessary to distinguish medium flow direction or installation orientation?
The valve supports double flange connection, single flange installation, and installation in any orientation. Thanks to its bidirectional sealing capability, there is no need to limit the valve orientation to a single medium flow direction during installation; the installation position should still be determined based on pipeline layout, actuator space, and on-site maintenance conditions.
What are the features of this butterfly valve in terms of long-term operation and maintenance?
The body and disc are precision machined, helping to reduce operating torque and extend service life; the shaft is fitted with three bearings to suppress shaft deflection and maintain positioning accuracy. The valve is maintenance-free in design, all components are replaceable, and the valve is disassemblable and supports material recycling.
