Bellows sealed globe valves are a type of valve with excellent sealing performance. The structural feature is a dual seal, which can perfectly isolate fluid and air, achieving zero leakage. The use of bellows sealed shut-off valves on pipelines is very common.

Why does bellows globe valve KHWJ40F1.6 have good sealing? The sealing principle of globe valves with corrugated pipes is to utilize the elastic deformation ability of the corrugated pipes and their self recovery characteristics after compression. When the valve is closed, a sealing surface is formed between the valve disc and the valve seat with corrugated pipes, and the corrugated pipes are compressed and deformed by hydraulic pressure. Bellows accumulate energy while compressing and deforming. When the bellows is under the pressure of the internal medium, and its elastic deformation force is greater than the medium pressure, the bellows will spring up naturally to push the valve disc away, and the internal medium can flow freely. When the valve needs to be closed, the bellows retracts and the valve disc returns to its original position, thus achieving the closure and opening of the valve.

During operation, the valve stem of the KHWJ40F1.6 bellows globe valve does not rotate, and the valve disc closes quickly, resulting in a small opening and closing force. The valve disc has a good streamlined structure, good elasticity and compensation ability. The flow channel structure is reasonable, which can effectively prevent accidents caused by fluid backflow or improve the system’s performance. Its advantages include small leakage, long service life, and reliable sealing. Safe and reliable use.
