Metal Bellows and Safety Packing
Supra MD: PN 63 / 100 / 160
ARI-FABA: Bellows-Sealed Globe Valves for Industrial Isolation
ARI FABA stop valves are engineered for open/close on-off service in process lines. Their metallic bellows seal isolates the stem from the process media, mitigating the risk of fugitive emissions—especially in steam systems and thermal fluid circuits. Designed strictly for on-off isolation, these shut-off valves are not intended to replace a control valve when accurate flow modulation is required. Count on VAMECA’s technical expertise to help you select the ideal configuration, end connections, materials, and options tailored to your specific operating conditions.
01
Stem Sealing
The metal bellows isolates the process media from the stem outlet. A secondary graphite packing provides an added safety barrier, offering dependable protection particularly for steam and thermal fluid systems.
02
Metal-to-Metal Seating
The conical plug provides positive shut-off against a metal seat. For the Supra MD, ARI specifies a Stellite seat and Class A seat leakage rate in accordance with EN 12266-1.
03
Visual Valve Position Indication
On FABA Plus and Supra I ANSI models, the position indicator comes standard. It enables visual verification of the valve position during routine maintenance rounds and servicing.
04
Actuation ready
Bellows-sealed globe valve line for industrial utilities and process applications. ANSI models are showcased with full ASME specifications and original manufacturer documentation.
Three FABA designs, from Class 150 to PN 160
The FABA Plus and Supra I models with ASME flanged connections cover sizes from NPS ½ to 10 in Class 150 or 300. For higher pressure ratings, the FABA Supra MD is engineered for PN 63, 100, and 160, from DN 10 to DN 100, featuring DIN/EN connections.

Selecting the Right FABA Valve: ASME Class, PN Ratings, Materials, and End Connections
Size isn't the only factor: properly distinguish ASME Class ratings from PN designations, then evaluate differential pressure, design temperature, and body material.
Selection Criteria
Pressure / Temperature
The FABA Plus and Supra I are available with ASME flanged ends in Class 150 and 300. The Supra MD is offered in PN 63, 100, and 160 ratings in accordance with the DIN/EN standard. Maximum allowable pressure also depends on operating temperature and material selection.
Body Materials
The flanged ANSI configurations shown feature SA216 WCB cast steel. The Supra MD is also available in 1.0460 forged steel, 1.0619+N cast steel, and high-temperature alloy steels.
Connection Type
The FABA Plus and Supra I ANSI models feature ASME flanges and face-to-face dimensions engineered for their specific pressure class. The Supra MD is available with DIN/EN flanges or butt-weld ends; please note that these end connections are not directly interchangeable.
Sealing and Operations
Stem Bellows
316Ti stainless steel bellows on FABA Plus and Supra I ANSI. The FABA Supra MD features a multi-ply bellows design isolated outside the flow path.
Emergency Packing
A pure graphite packing backs up the primary bellows seal on ANSI Plus/Supra I configurations and the Supra MD line.
Operation and Maintenance
The FABA Plus features a non-rising handwheel with a position indicator, while the Supra MD is engineered with a rising handwheel. Balanced plugs ensure smooth, reliable operation on select high differential pressure configurations.
Provide us with the NPS or DN, media, pressure, temperature, differential pressure, and desired connection type. VAMECA will direct you to the ideal FABA design and all relevant technical documentation.
Where should an ARI-FABA stop valve be used?
From boiler plants to process piping networks, the key advantage of the FABA valve is dependable isolation achieved through a metal bellows stem seal. The selected series is engineered to match your specific pressure, temperature, and media requirements.
Manual Operation, Actuation, and Integration of FABA Bellows-Sealed Valves
A FABA is an isolation valve, not a control valve. ARI provides detailed documentation on manual operators, position indicators, and actuation options for select configurations.
Handwheel Operated
On the FABA Plus, the handwheel is non-rising with a position indicator. The Supra MD features a rising handwheel and an outside screw and yoke (OS&Y) design.

Installation and Accessories
How to Select the Right ARI FABA Valve
Selecting the right model involves more than just nominal diameter. Four technical criteria guide the proper selection of a FABA valve and its seamless integration into your existing system.
Metal bellows
Pressure and Temperature
FABA Plus and Supra I: flanged versions available in ASME Class 150 or 300. Supra MD: DIN/EN designs available in PN 63, 100, or 160. Maximum allowable pressure is also dependent on temperature and body material.
Pressure Classes
End Connections and Overall Dimensions
ASME or DIN/EN flanges, NPT threading, and welded connections are available depending on the product line. For replacements, face-to-face dimensions and operational clearance must also match your existing installation.
End Connections
Differential Pressure
At high differential pressures, specific diameters require a balanced plug to facilitate opening. ARI therefore designates a required flow direction: the actual ΔP is a critical selection criterion.
