FAQ
What nominal sizes, pressure, and temperature ranges is the EBRO Z011-AS wafer butterfly valve suitable for?
The Z011-AS has nominal sizes from DN 50 to DN 300 and a maximum operating pressure of 3 bar. The operating temperature range is -10°C to +100°C; however, the actual permissible temperature depends on the pressure, medium, and valve material combination and should be confirmed for the specific operating conditions.
Can the Z011-AS wafer butterfly valve be used for modulating service?
Yes. The valve can be used for on-off control as well as modulating service. During selection, the valve size and control solution should be determined based on the medium characteristics, target flow rate, differential pressure, and required control accuracy.
Which pipe flange standards are compatible with the Z011-AS?
The valve uses a wafer connection and can be installed with EN 1092 PN 6, PN 10, and PN 16, ASME Class 150, and AS 4087 PN 16 flanges. Compatible flange sealing faces include EN 1092 Form A/B and ASME RF and FF.
Are there any restrictions on the installation orientation of the Z011-AS?
The Z011-AS can be installed in any orientation and arranged according to the piping layout and available space for the on-site actuator. During installation, ensure proper flange alignment and adequate pipe support, and prevent installation stresses from acting on the valve body.
What are the sealing performance and maintenance characteristics of the Z011-AS?
The valve's leakage rating complies with EN 12266 Leakage rate A and ISO 5208 Category 3. Its design incorporates triple shaft bushings and a replaceable seat, and the product documentation identifies it as maintenance-free. The valve can be disassembled, and its materials can be recycled.
