GS-C25 Bellows Sealed Globe Valve, DIN 3356, DN50, PN16, RF

The GS-C25 Bellows Sealed Globe Valve, manufactured according to DIN 3356 standards, features a carbon steel body for durability and corrosion resistance. With a DN50 (2-inch) size and a pressure rating of PN16, Class 150 LB, this valve is designed for reliable fluid control in moderate-pressure systems. It comes with RF flanged ends for secure connections and is handwheel operated for easy manual control.

Product Name: GS-C25 Bellows Sealed Globe Valve
Design Standard: DIN 3356
Body Material: GS-C25
Size: DN50, 2 Inch
Pressure: PN16, Class 150 LB
End Connection: RF Flanged
Operation: Handwheel

The Bellows Sealed Globe Valve integrates advanced foreign technology, featuring a double bellows design welded to the valve stem to ensure stable operation. This design minimizes valve vibration caused by plug movement, ensuring zero leakage from the stem, even at high temperatures, as the stem does not come into contact with the medium. The valve's construction provides sufficient strength and toughness, enabling it to withstand tens of thousands of cycles.
The ergonomically designed handwheel contributes to a longer service life and facilitates easy operation. The valve employs a plug-shaped design for opening and closing, with either a flat or conical sealing face. It moves straight along the fluid's centerline, making it one of the most widely used and durable valves in industrial applications. Its design minimizes friction during operation, ensuring longevity and ease of manufacturing.
