DIN 3356 Globe Valve, GS-C25, DN50, PN40, Bellows Sealed, RF

Product Name: DIN 3356 Globe Valve, Bellows Sealed
Design Standard: DIN 3356
Body Material: GS-C25, Carbon Steel
Size: DN50, 2 Inch
Pressure: PN40, Class 300 LB
End Connection: RF Flanged
Operation: Handwheel

The bellows-sealed globe valve integrates advanced foreign technology, utilizing a double bellows design welded to the valve stem. This design ensures stable operating performance while minimizing valve vibration caused by plug movement. At high temperatures, the stem remains isolated from the medium, guaranteeing zero leakage. The valve is engineered for exceptional strength and toughness, allowing it to operate reliably for tens of thousands of cycles.

The ergonomically designed handwheel enhances operational ease, offering extended service life and convenient handling. The bellows cut-off valve features a plug-shaped design with flat or conical sealing faces. The valve moves along the centerline of the fluid, providing efficient flow control. This design is highly popular due to the minimal friction between sealing surfaces during operation, ensuring durability and reliability. It offers a compact opening height, is easy to manufacture, and has straightforward dimensional requirements.
