Because the pneumatic angle seat valves in a nitrogen generator often open and close, their quality is very important. We come across an increasing number of cheap valves in the market, which are not suitable. It often happens that we, or one of our partners, have to replace these valves, sometimes already after 2-3 years, making a bargain suddenly unattractive and bringing owners down to earth with a shock. From 30 years of experience we can tell you: don’t take the risk, because it’s not worth it. Better work with quality parts. We use angle seats from a renowned German brand. The chance of malfunctioning is then virtually eliminated.
