ARI-FABA®-Plus 35.046 Metal Bellows Valve DN20 PN40

ARI-FABA®-Plus 35.046 Metal Bellows Valve DN20 PN40: Zero Emission Solution for High Pressure and Temperature

ARI-Armaturen is a world-renowned German brand of industrial valves and armatures. ARI-FABA®-Plus 35.046 Metal Bellows Valve is an advanced technology Metal Bellows Valve designed to provide absolute tightness (100% external emission sealing) and precise flow control, especially in the control of very high temperature, high pressure and hazardous fluids.

While the Metal Bellows Valve is used in medium-sized lines with the size DN20 (Nominal Diameter 20 mm / 3/4 inç) , the pressure class PN40 (40 bar)

indicates that it can operate safely up to 40 bar nominal pressure. "Metal bellows" structure uses a flexible metal bellows to ensure stem sealing, unlike conventional packing valves.

ARI-FABA®-Plus 35.046 What is Metal Bellows Valve and How Does It Work?

This metal bellows valve controls the passage of the fluid with a disc (clapper) that moves linearly (up-down) when the flywheel is turned. The disc regulates or interrupts the flow by approaching or moving away from the seat on the valve body. The metal bellow integrated into the valve shaft flexes during the movement of the shaft and completely closes the gap between the shaft and the external environment, thus preventing the leakage of the fluid (zero external emission).

• ARI-FABA®-Plus 35.046 Metal Bellows Valve Highlights and Advantages: Zero External Emission:

• The risk of leakage is eliminated thanks to the metal bellows and additional graphite safety seal. This guarantees compliance with international environmental protection standards such as TA-Luft. Maintenance-Free:

• Thanks to its bellows structure, there is no need to tighten or replace the traditional shaft seal, which reduces operating costs and minimizes unplanned downtime. High Pressure and Temperature Resistance:

• Provides reliable performance in PN40 pressure class and at high temperatures up to 450°C depending on the material. Durable Material: Body and cover are made of .0619+N Steel Casting

• (Cast Steel), resistant to high pressure and temperature. The bellows and shaft are made of stainless steel (1.4571 / 1.4021). Precise Flow Control:

• Marginal seat valve design allows very precise adjustment of fluid flow rate. Connection Type:

• Flanged and butt weld neck connection options are available. Compliance with International Standards:

Manufactured in accordance with standards such as PED 2014/68/EU CE certified and EN ISO 15848-1/TA-Luft.

ARI-FABA®-Plus 35.046 Metal Bellows Valve Usage Areas:

• This Metal Bellows Valve is commonly used in industrial applications where precise flow control and durability are important:

• Power generation and steam lines

• Refineries and petrochemical plants

• Chemical, food and paper mills
