GS-C25 Angle Globe Valve, DIN 3356, DN50, PN16, Bellows Seal

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

The Bellows Sealed Globe Valve incorporates advanced foreign technology, featuring a double bellows design welded to the valve stem to maintain stable operating performance and prevent valve vibration caused by plug movement. At high temperatures, the stem does not contact the medium, ensuring zero leakage. The design guarantees sufficient strength and toughness, enabling the valve to endure tens of thousands of operating cycles.
The ergonomically designed handwheel offers a longer service life while ensuring ease of operation. The bellows cut-off valve operates with a plug-shaped valve, with either a flat or conical sealing face. The valve moves straight along the fluid’s center line, making it one of the most widely used types. It is favored for its minimal friction between sealing surfaces during operation, ensuring durability, a compact opening height, ease of manufacturing, and simplified dimensioning.
