GS-C25 Y Type Globe Valve, DIN 3356, DN50, PN16, Bellow Seal

The GS-C25 Y Type Globe Valve is a high-quality valve designed for precise flow control. It features a carbon steel body and adheres to DIN 3356 standards. This valve is bellows sealed, ensuring zero leakage and enhanced safety. With a size of 2 inches (DN50) and a pressure rating of PN16 (Class 150 LB), it is suitable for a wide range of industrial applications. The valve is handwheel operated for easy control and is equipped with RF flanged ends for secure and reliable connections.

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

Bellows Sealed Globe Valves incorporate advanced foreign technology and utilize a double bellows design, welded to the valve stem, to maintain stable operation and prevent vibration caused by valve plug movement. At high temperatures, the stem does not contact the medium, ensuring zero leakage at the stem. The design also ensures sufficient strength and toughness, enabling the valve to operate tens of thousands of times. The handwheel is ergonomically designed for longer service life and ease of operation. The opening and closing mechanism of the bellows cut-off valve features a plug-shaped valve with flat or conical sealing faces. The valve moves straight along the center line of the fluid, making it one of the most widely used valve types. It is favored for its low friction between sealing surfaces during operation, durability, minimal opening height, ease of manufacture, and manageable dimensions.
