A system of valves connected to a device through which compressed air flows so as to allow, with the bypass valve closed and the inlet and outlet valves open, air to flow through the device, and with the bypass valve open and the inlet and outlet valves closed, air to flow through the pipeline and a bypass valve so that during this time you can, for example, operate a device powered by compressed air without having to uninstall it from the compressed air network. This solution is recommended for tanks in the compressor room in order to inspect them regularly without interrupting the operation of the system. It is recommended to use similar systems for control valves, filter systems or dryers (so that the control valves, filter cartridge, dryers can be replaced without stopping the system).
