Extended Stem Globe Valve, DIN 3356, A351 CF8M, DN100, PN16

Product Name: Bellows Sealed Globe Valve, Extended Stem
Design Standard: DIN 3356
Body Material: ASTM A351 CF8M
Size: DN100, 4 Inch
Pressure: PN16, Class 150 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. This design maintains stable operating performance and prevents valve vibration caused by valve plug movement. At high temperatures, the stem does not come into contact with the medium, ensuring zero leakage. The valve also ensures sufficient strength and toughness, capable of withstanding tens of thousands of cycles.

The handwheel is ergonomically designed, offering a longer service life and easy, convenient operation. The opening and closing of the bellows cut-off valve involve a plug-shaped valve. The sealing face is either flat or conical, and the valve moves straight along the centerline of the fluid. This type of valve is widely used due to its small friction between sealing surfaces during opening and closing, making it relatively durable. It also features a low opening height, easy manufacturing, and straightforward dimensioning.
