EN 1.0619 Globe Valve, DIN 3356, DN50, PN40, Bellows Sealed

Product Name: Extended Stem Bellows Seal 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

Bellows-Sealed Globe Valves incorporate advanced foreign technology and feature a double bellows design welded to the valve stem, ensuring stable operation and preventing vibrations caused by valve plug movement. At high temperatures, the stem does not come into contact with the medium, ensuring zero leakage at the stem. The valve is designed for durability, with sufficient strength and toughness to handle tens of thousands of cycles.

The ergonomically designed handwheel enhances ease of operation and extends service life. The bellows cut-off valve operates with a plug-shaped valve, featuring a flat or conical sealing face. The valve moves straight along the fluid's centerline. This type of valve is widely used due to its low friction between sealing surfaces during operation, making it durable and efficient. Its compact opening height, ease of manufacture, and straightforward dimensions contribute to its popularity.
