DIN 3202 Bellows Seal Globe Valve GS25 CF8

The bellows globe valve adopts a bellows structure inside, and the lower end of the stainless steel bellows is welded to the valve stem through a stainless steel gasket to prevent the process fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The double sealing design will avoid leakage if the bellows fails the valve stem packing. The bellows is welded to the valve stem to maintain stable operation performance and avoid the valve stem vibration caused by the vibration of the valve disc. It is suitable for pipelines of steam, flammable, explosive, heat-conducting oil, high-purity, toxic and other media.

Comparison of bellows seal globe valve and ordinary globe valve
1. Double sealing design (bellows + packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards.
2. There is no fluid loss, reducing energy loss and improving plant equipment safety.
3. Long service life, reduce maintenance times and reduce operating costs.
4. The sturdy and durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.
5. The gas medium valve seat adopts PTFE soft sealing material to improve the sealing performance of the valve.
6. The valve seat with high temperature resistance ≤425℃ adopts conical hard seal. Achieve zero leakage of air tightness.
With the continuous rise of labor costs, reducing labor is what more and more companies want. There is such a bellows globe valve that can make it easier for workers to switch on and off. The product has a longer service life and a better sealing performance. There is reason to believe it. prospects will become more and more broad.
