Main advantages of bellows globe valve products

The inside of the bellows globe valve is a bellows. The lower end of the stainless steel bellows is welded to the valve stem to prevent the valve stem from being corroded by the fluid. The other end is located between the valve body and the bonnet for static sealing. The double sealing design also prevents leakage of the bellows when the valve stem packing fails. The bellows is welded to the valve stem to maintain stable operating performance and prevent the valve stem from vibrating due to the vibration of the valve plug. It is suitable for medium pipelines such as steam, flammable, explosive, heat transfer oil, high purity, toxic, etc.

The main advantages of the bellows globe valve product:

1. The key component of the bellows globe valve is the metal bellows. The lower end is automatically roll-welded between the valve stem assembly, and the upper end is automatically roll-welded with the connecting plate, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem;

2. The valve disc adopts a conical design. The sealing surface and the medium form a streamline, and the sealing performance is better and the service life is longer;

3. Double sealing design with bellows (bellows + packing)
