Air Steam Pn40 Bellows Seal Globe Valve Cast Steel Cast Iron

Air Steam cast steel cast iron Bellows Seal Globe Valve

1. Stainless steel globe valve has a Simple structure, manufacture and maintenance more convenient
2. Good sealing, Long service life
3. Operation: manual, gear operated, motor operated, pneumatic operated
4. The Globe valve stem and valve seat sealing surface axis vertical.
5. Open or close the valve stem travel relatively short, and very reliable cutting action, making this valve is suitable for medium and cutting off or regulating use

Product advantage

1. The bellows seal the globe valve, the key component of which is the metal bellows. The lower end and the valve stem assembly are automatically hobbing welded, and the upper end is automatically hobbing welding with the connecting plate to form a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem

2. Valve plate adopts conical design, sealing surface and medium form a flow line, better sealing performance, longer service life

3. Double seal design, avoid leakage, in line with international seal standards

4. The valve cover is equipped with a grease joint, which can directly lubricate the valve stem, nut and shaft sleeve.

The bellows are welded to the valve stem to maintain stable operating performance and avoid vibration of the stem caused by the vibration of the valve plug. It is most suitable for the pipeline with steam, flammable, explosive, thermal oil, high purity, toxic and other media.
