Y Type Bellows Sealed Globe Valve, DIN 3356, EN 1.0619, DN50

Product Name: Y Type Bellows Sealed Globe Valve
Design Standard: DIN 3356
Body Material: EN 1.0619
Size: DN50, 2 Inch
Pressure: PN40, Class 300 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 for enhanced operational stability. This design prevents valve vibration caused by plug movement. At high temperatures, the stem remains isolated from the medium, ensuring zero leakage and maintaining long-term reliability. The valve is designed for durability, capable of enduring tens of thousands of cycles while maintaining strength and toughness.
The ergonomic handwheel ensures ease of operation and extended service life. This valve operates with a plug-shaped disc, featuring either a flat or conical sealing face, moving linearly along the fluid’s centerline. Due to minimal friction between sealing surfaces, it is highly durable, requires low opening height, and is easy to manufacture with compact dimensions, making it one of the most widely used globe valves.
