Bellows Sealed Globe Valve, DIN 3356, GS-C25, DN50, PN16, RF

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

The Bellows-Sealed Globe Valve uses advanced technology with a double bellows design welded to the valve stem for stable performance. This design helps prevent vibration caused by the valve plug and ensures the stem does not touch the medium at high temperatures, eliminating the risk of leakage. It’s built to be strong and tough, capable of withstanding tens of thousands of cycles.

The valve features an ergonomically designed handwheel for easy operation and a longer service life. The bellows cut-off valve works with a plug-shaped valve, and its sealing surface can be flat or conical. The valve moves smoothly along the centerline of the fluid. It’s widely used due to its low friction between sealing surfaces, which makes it durable and efficient. Its small opening height, simple manufacturing process, and easy-to-make dimensions contribute to its popularity in many applications.
