DIN 3356 Y Globe Valve, GS-C25, DN80, PN25, Bellows Sealed

Product Name: Y Type Bellows Sealed Globe Valve
Design Standard: DIN 3356
Body Material: GS-C25
Size: DN80, 3 Inch
Pressure: PN25, Class 300 LB
End Connection: BW End
Operation: Handwheel

Bellows Sealed Globe Valves incorporate advanced foreign technology with a double bellows design welded to the valve stem, ensuring stable operation and preventing vibration caused by valve plug movement. At high temperatures, the stem remains isolated from the medium, guaranteeing zero leakage. The valve is designed for high strength and toughness, allowing for tens of thousands of cycles. The ergonomically designed handwheel enhances ease of operation and prolongs service life. The bellows cut-off valve features a plug-shaped design, with flat or conical sealing surfaces, and moves in a straight line along the fluid's centerline. Known for minimal friction between sealing surfaces, these valves are durable, require low opening height, are easy to manufacture, and offer reliable performance in a wide range of applications.
