Check Valve, Soft Seal or Metallic Seal?

简而言之,止回阀的作用在管道系统em is to prevent backflow of media. Check valve alsocan be divided into hard seal check valve and soft seal check valve--soft seal check valve sealing performance isoutstanding and it can reach zero leakage, butcanonlybe putin the normal temperature and low pressure pipeline, while hard seal check valve can. And due to the manufacturing process,hard seal check valvealwayshas a certain amount of leakage. But the advantage of hard seal is that it can adapt to high temperature and high pressure environment. Therefore, you can nothave a frivolous judge that the hard seal check valve is good or soft seal check valveis. Both have their advantages as long as they are correctly installed in the appropriate working conditions on the pipeline. So how to make a choice between them two? 1. Soft seal The spin or seat of soft seal check valve is made of non-metallic materials (mainly PTFE, and rubber, etc.). It enjoys remarkable sealing performance, but sustains reproof that it may leave more or less residues (such as welding slag, iron filings, etc.) in the pipeline system as they flow through the regulating valve, which is prone to hurt the valve seat or spool. Therefore, choosing soft seal check valve means extra notices on the purity of medium and cleanness of the pipeline before commissioning. 2. Hard seal Hard seal check valve would adopts welded wear-resistant alloy on its sealing surface which balances sealing performance and the service life and reliability. Although it dwarfs as a competitor with soft seal check valve when it comes to sealing performance, it is enough to meet the needs of most working conditions, and it enjoys durable and longer service life.
