Application scenarios
Main process lines for acids, alkalis, and highly corrosive media in chemical plants
Used for shutoff and flow control of acids, alkalis, and other highly corrosive media in large-diameter main lines of chemical plants. The valve features a PTFE-lined construction and is equipped with the EBRO-Safety sealing system, suitable for DN 350 to DN 900 pipelines.
Conveyance and isolation lines for toxic chemical media
Used for pipeline sections that convey, distribute, and isolate toxic or corrosive chemical media in chemical production plants. Suitable for large-diameter pipelines from DN 350 to DN 900, the valve features a PTFE-lined construction and the EBRO-Safety sealing system, with sealing performance complying with EN 12266 Leakage rate A.
Pharmaceutical process liquid conveyance systems
Used for pipelines that convey, isolate, and regulate process liquids in pharmaceutical production. Product contact materials comply with FDA and EG 1935/2004 requirements, making it suitable for large-diameter process piping configurations where material contact compliance is a concern.
Selection points
Large-diameter PTFE-lined valve for highly corrosive or highly toxic media
Nominal diameters from DN350 to DN900 with a PTFE-lined construction; product documentation explicitly states suitability for highly corrosive or highly toxic media applications.
Compatible with multiple flange standards
Connecting flanges correspond to EN 1092 PN10/16, ASME Class 150, ASME B16.47 Series A and Series B, and AS 4087 standards; verify the selection against the existing pipeline flange standard.
Vacuum application limits differentiated by nominal diameter
Vacuum applications must be selected by nominal diameter: DN350 to DN600 up to 200mbar absolute pressure; DN700 to DN900 up to 500mbar absolute pressure, the latter conditional on a silicone rubber liner.
EBRO-Safety sealing system supports environmental safety requirements
The valve is equipped with the EBRO-Safety sealing system, which product documentation describes as serving environmental safety; it can be considered a sealing safety selection factor for highly corrosive or highly toxic media applications.
Supports installation at any angle
Product documentation explicitly states that the valve can be installed at any angle, which can serve as a mounting orientation selection criterion when on-site layout is restricted.
FAQ
What media and operating conditions is the EBRO PTFE-lined butterfly valve T212-A suitable for?
The T212-A features a PTFE-lined construction and is suitable for highly corrosive or highly toxic media. Its operating temperature range is -40°C to +200°C, but the actual allowable temperature must be determined based on both nominal diameter and media pressure; the maximum working pressure is 6 bar, and up to 10 bar with special designs.
What is the T212-A's scope of application in vacuum systems?
DN 350 to DN 600 sizes can be used in vacuum applications with an absolute pressure down to 200 mbar; DN 700 to DN 900 sizes can be used in vacuum applications with an absolute pressure down to 500 mbar, with that range corresponding to a silicone rubber liner configuration.
Which flange standards can the T212-A connect to?
The valve can be used with EN 1092 PN 10/16, ASME Class 150, ASME B16.47 Series A and Series B, and AS 4087 flanges; flange sealing faces are compatible with EN 1092 Form A/B as well as ASME RF and FF. Face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1.
What are the sealing performance and environmental design features of the T212-A?
The sealing performance of the T212-A complies with EN 12266 Leakage rate A, and it uses the EBRO-Safety sealing system to support environmental safety requirements. Material contact compliance meets FDA and EG 1935/2004; special designs can comply with TA-Air/VDI 2440 requirements.
Is the T212-A restricted by mounting orientation during installation?
The valve can be installed at any angle. Its top flange complies with EN ISO 5211, facilitating mating with the corresponding actuator interfaces; the valve features a two-piece body design and is specified as maintenance-free, removable, and made of recyclable materials.
