The bellows sealed globe valve incorporates advanced foreign technology, featuring a double bellows design that is welded to the valve stem. This design maintains stable operating performance and prevents valve vibration caused by plug movement. At high temperatures, the stem does not come into contact with the medium, ensuring zero leakage. The valve also offers sufficient strength and toughness, capable of withstanding tens of thousands of cycles.
The handwheel is ergonomically designed for a longer service life and easy, convenient operation. The opening and closing mechanism of the bellows globe valve involves a plug-shaped valve with a flat or conical sealing face. The valve moves in a straight line along the centerline of the fluid flow. This type of valve is widely used due to its small friction between sealing surfaces during operation, durability, low opening height, ease of manufacturing, and straightforward dimensional requirements.

Product Features

Reasonable Structure, Reliable Sealing, Excellent Performance, and Beautiful Appearance: The bellow-sealed globe valves are designed with a rational structure, ensuring reliable sealing and excellent performance. They also feature an aesthetically pleasing appearance.
Broad Material Availability: We offer a wide range of cast body and trim materials for its bellow valves. This versatility often provides the most economical solution for various process and steam systems.
Sealing Surface: The sealing surfaces are hard-faced with Cr.Alloy, which is resistant to wear, corrosion, and friction. This treatment ensures a longer service life and tight shut-off double sealing for perfect operation.
Stem: The stem undergoes quenching and tempering, followed by nitriding treatment. These processes ensure excellent anti-corrosion and anti-friction properties.
Optional Stem Position Indicator: An optional stem position indicator is available to provide a more direct visual indication of the valve's on/off status.
