Application scenarios
Pharmaceutical process media transfer piping
Used for isolation or fluid control in pharmaceutical process media transfer piping. The valve can be supplied with materials compliant with U.S. FDA standards and features a removable design. Specific suitability depends on the medium and material configuration.
Coating production line media piping
Used for media transfer or isolation piping in coating production lines that are sensitive to silicone contamination. Silicone-free treated valves are available to support contamination-control requirements in coating processes.
Water supply and wastewater treatment facility piping
Used in DN 350 to DN 600 flanged piping at water supply and wastewater treatment facilities for shut-off and isolation of water conveyance pipelines. The valve uses a double-flanged connection, has a maximum working pressure of 10 bar, and meets EN 12266 Leakage rate A and ISO 5208 Category 3.

FAQ
What pipe sizes, pressure ratings, and temperature ranges is the Z612-A double-flanged butterfly valve suitable for?
The Z612-A has a nominal diameter range from DN 350 to DN 600 and a maximum working pressure of 10 bar. Its operating temperature range is from -40°C to +200°C, but the actual permissible temperature must be confirmed based on pressure, conveyed medium, and valve material.
Which flange standards and sealing face types can be used with the Z612-A?
The valve connection flanges are compatible with EN 1092 PN 10/16 and ASME Class 150. Flange sealing faces can be matched with EN 1092 Form A/B, as well as ASME RF or FF types. Verify the site flange standard, pressure rating, and sealing face type during selection.
Does the Z612-A installation length facilitate replacement of existing butterfly valves?
The face-to-face dimensions of the Z612-A comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1. For piping locations using these dimension series, the valve face-to-face dimension can be checked against the existing installation space.
What are the leakage class and sealing design features of the Z612-A?
The valve meets EN 12266 Leakage rate A and ISO 5208 Category 3. The disc sealing surface is mirror-polished, and the disc and shaft feature an integrated design. Actual sealing suitability should still be confirmed based on the medium, temperature, pressure, and material compatibility.
Is the Z612-A suitable for actuator installation and use in the coating industry?
The Z612-A is equipped with a top flange compliant with EN ISO 5211 and can be fitted with actuators using compatible interfaces. For use in the coating industry, silicone-free treated valves are available. TA-Air/VDI 2440 certification and materials compliant with U.S. FDA standards are also available. Specific configurations must be confirmed according to the actual model and application conditions.
