In the process of using the solenoid valve, there are a few points that most apprentices pay no attention to. The next two talk about these precautions. Installation Precautions. When the solenoid valve used in pneumatic systems, pneumatic components connected with the general use of raw material tape (ie, sealing tape) winding. The same is to complete the function of the seal winding. However, you experienced friends will certainly encounter such a phenomenon: it is obviously a brand new component, but when the test machine is always leaked. One of the big reasons, the most common one, is that when the raw material tape is wound, the correct method is not used and some of the raw material tapes go to the gas path. This requires attention to a positive and negative sequence when wrapping the raw tape. Please apprentice to this point to try and experience. For large current solenoid valve must be installed in the front relay. Especially in the hydraulic system of the solenoid valve, because the current is large, if you do not install the relay, the solenoid valve life will be short.
