It may sometimes be an advantage to fit a gauge isolator valve, which isolates the gauge from the air pressure, except when it is required to take a reading. Such a valve may be single or multi-station. In the off position the gauge is vented; in one of the operative positions it can select the station to be read. The fitting of such a valve extends the life of the gauge.
