Angle Bellows Sealed Globe Valve, DIN 3356, GS-C25, DN150

Product Name: Angle Bellows Sealed Globe Valve
Design Standard: DIN 3356
Body Material: Carbon Steel GS-C25
Size: DN150, 6 Inch
Pressure: PN16, Class 150 LB
End Connection: RF Flanged
Operation: Handwheel

The Bellows Sealed Globe Valve incorporates advanced foreign technology with a double bellows design, welded to the valve stem to ensure stable operation and prevent vibration caused by valve plug movement. At high temperatures, the stem remains isolated from the medium, guaranteeing zero leakage. The valve is designed for durability, capable of enduring tens of thousands of cycles with sufficient strength and toughness. The ergonomically designed handwheel ensures ease of operation and a longer service life. The valve operates with a plug-shaped design, featuring either a flat or conical sealing face, and moves along the centerline of the fluid. Its low friction during operation makes it highly durable, with a small opening height, easy manufacturing, and simple dimensional adjustments. This makes it one of the most widely used and popular valve types.
