Application scenarios
Flow Control and Isolation in Gas Distribution Pipelines
Used for opening, closing, and isolating process sections of medium flow in gas distribution pipelines. The valve features flanged connections and sealing to EN 12266 Leakage rate A and ISO 5208 Category AA, and operates within the product's specified temperature and pressure ranges.
Selection points
Working Temperature and Maximum Pressure Limits
This model has a working temperature range of -20°C to +60°C and a maximum working pressure of 16 bar. Actual selection must be confirmed in consideration of the medium, pressure, and material conditions.
Lug Type Body Construction
This model features a lug type butterfly valve design. Suitability should be confirmed based on the piping connection method, nominal diameter, and pressure class during selection.
Multi-Standard Flange and Sealing Face Compatibility
Connecting flanges support EN 1092 PN 6/10/16, ASME Class 150, and AS 4087 PN 16; flange sealing faces support EN 1092 Form A/B as well as ASME RF and FF.
EN ISO 5211 Standard Top Flange Interface
The valve top flange conforms to EN ISO 5211 and can serve as the basis for selecting the mechanical mounting interface of an actuator.
Shut-Off Sealing Class
Sealing performance complies with EN 12266 Leakage rate A and ISO 5208:2015 Category AA. These ratings can be used during selection to verify the valve's tightness requirements for shut-off.
FAQ
What are the applicable diameters and pressure range of the Z014-A GAS lug type butterfly valve?
The Z014-A GAS covers nominal diameters from DN 20 to DN 600 with a maximum working pressure of 16 bar. The DN 20 size is only available for PN 10/16 pressure classes. During selection, the valve pressure class should be matched with the pipeline flange standard, medium conditions, and operating conditions.
Which flange standards can the Z014-A GAS be installed with?
The valve is compatible with EN 1092 PN 6, PN 10, and PN 16, ASME Class 150, and AS 4087 PN 16 flanges. Flange sealing faces correspond to EN 1092 Form A/B as well as ASME RF and FF types. Before installation, the flange pressure class, sealing face type, and dimensional compatibility should be verified.
Which face-to-face standards do the installation dimensions of the Z014-A GAS follow?
The face-to-face dimensions of the Z014-A GAS comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1. For valve replacement or new pipeline design, the reserved pipe length and valve installation space can be verified against these standards.
According to which standards is the sealing performance of the Z014-A GAS rated?
The valve's sealing class complies with EN 12266 Leakage rate A and ISO 5208:2015 Category AA. These ratings evaluate sealing performance in the closed position; actual performance in service must still be confirmed in consideration of the medium, pressure, temperature, and actual installation conditions.
What is the working temperature range of the Z014-A GAS, and what should be considered during selection?
The Z014-A GAS has a working temperature range of -20°C to +60°C. Temperature capability depends on the actual working pressure, the medium, and the valve materials. Therefore, in operating conditions close to the temperature or pressure limits, confirmation should be based on the actual model and application conditions.
