Application scenarios
Pipeline Fluid Shut-Off and Flow Control
This wafer type butterfly valve is used for shut-off and flow control of fluids in pipelines. It supports actuator mounting via the EN ISO 5211 interface and is suitable for a maximum working pressure of 16 bar and a working temperature range of -40°C to +200°C, with actual service conditions depending on pressure, medium and materials.
Selection points
Diameter and Maximum Working Pressure Range
Nominal diameters cover DN 20 to DN 1000 with a maximum working pressure of 16 bar; the DN 20 size is only available in PN 10/16 pressure ratings, so the matching of diameter and pressure rating should be verified during selection.
Multi-Standard Flange Connection Compatibility
Supports EN 1092 PN 6/10/16, ASME Class 150 and AS 4087 PN 16 connection flanges, and is compatible with EN 1092 Form A/B as well as ASME RF and FF flange sealing faces.
Standardized Actuator Mounting Interface
The top flange features an EN ISO 5211 standard interface for matching manual or automated actuation devices built to the same standard.
Class A Shut-Off Sealing Performance
The leakage class complies with EN 12266 Leakage rate A and ISO 5208:2015 Category AA, serving as a selection basis for pipeline applications that require tight shut-off.
Working Temperature Range and Service Constraints
The working temperature range is -40°C to +200°C; the actually permitted temperature must be determined in combination with the working pressure, medium and materials.
FAQ
Which pipeline flange standards can the Z011-A WATER wafer type butterfly valve be matched with?
The valve can be combined with EN 1092 PN 6, PN 10 and PN 16, ASME Class 150 and AS 4087 PN 16 flanges; the flange sealing faces are compatible with EN 1092 Form A/B and ASME RF and FF. Verify the pipeline flange standard, pressure rating and sealing face form during selection.
What are the applicable diameter, pressure and temperature ranges of the Z011-A WATER?
The series covers nominal diameters from DN 20 to DN 1000, of which the DN 20 size is only suitable for PN 10/16. The maximum working pressure is 16 bar; the working temperature range is -40°C to +200°C, but the actually permitted temperature depends on the medium, working pressure and valve material combination.
Which standards does the sealing performance of the Z011-A WATER comply with?
The valve's leakage class complies with EN 12266 Leakage rate A and ISO 5208:2015 Category AA. These two classes define the sealing requirements of the valve in the closed state and suit applications with explicit shut-off leakage control requirements.
Can the Z011-A WATER be fitted with pneumatic or electric actuators?
Yes. The valve features an EN ISO 5211 actuator mounting interface, which serves as the mounting and connection basis for manual operation or automated actuation. Actuator specifications should be confirmed based on the valve diameter, differential pressure, medium conditions and required mode of action.
Which standards should be used to verify the face-to-face dimensions of the Z011-A WATER?
The valve's face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20 and API 609 Table 1. For replacement installation or pipeline design, the valve face-to-face length and flange spacing can be verified against the corresponding standards.
