Bellows Sealed Globe Valve incorporates advanced foreign technology, featuring a double bellows design that is welded to the valve stem. This innovative design maintains stable operating performance and prevents valve vibration caused by plug movement. At high temperatures, the stem remains isolated from the medium, ensuring zero leakage. The valve is engineered with sufficient strength and toughness to withstand tens of thousands of switching cycles. The handwheel is ergonomically designed, offering a longer service life and easy, convenient operation. The opening and closing mechanism of the bellows globe valve features a plug-shaped valve with a flat or conical seal face. The valve moves in a straight line along the centerline of the fluid flow. This design is widely used and popular due to its low friction between sealing surfaces during operation, making it highly durable. The valve also benefits from a small opening height, ease of manufacturing, and straightforward dimensioning.
