Most of the damage to the bellow seal globe valve is not used because of the production process, on the contrary, because of mechanical compression and damage. Although the bellow seal globe valve have different levels of flexibility, with different coatings, and different PTFE guard, but, for all Bellow Seal Globe Valves are invisible from the outside wear (caused by the internal surface of the media corrosion and particle adhesion). Therefore, in order to avoid the production process due to aseptic diaphragm valve damage and was forced to stop production, in practice, usually the life of the prescribed period before the replacement bellows. As a result, both the number of mandatory replacement of bellows, or the resulting maintenance costs, or equipment downtime, than PTFE Bellow Seal Globe Valves is significantly more, and Bellow Seal Globe Valves Another advantage is that: for almost various processes of production processes.

bellow seal globe valve features:

1, a double seal design (bellows + fill) if the bellows failure, stem packing will prevent leaks, and sealing line with international standards

2, there is no fluid loss, reduce energy losses and improve the safety of plant equipment

3, long service life, reduced maintenance times, reducing operating costs

4, rugged bellows seal design to ensure zero leakage valve stem to provide the conditions for maintenance

5, the gas medium seat of PTFE soft sealing material to improve the tightness of the valve

6, temperature ≤ 425 ℃ using cone seal seat. To achieve zero leakage sealing performance
