Bellows Globe Valve

The bellows globe valve adopts a bellows structure internally, and the lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve bonnet to form a static seal. The double sealing design will prevent leakage if the bellows fails and the valve stem packing fails. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration due to valve plug vibration. Most suitable for pipelines with steam, flammable, explosive, thermal oil, high purity, toxic and other media.

Design Advantages

Bellows with packing and double sealing to prevent leakage

The bellows design does not require disassembly and replacement of packing, saving costs.

Circular valve disc design reduces friction between the base and the valve disc and increases service life

High sealing performance, reducing energy loss

Corrosion resistant and able to be used in a range of extreme environments

Multiple operating modes to choose from

Diversified selection of materials to increase strength
