A twin cylinder, automatic changeover regulator that provides a continuous gas supply to the installation. Supplied with two 20” pigtails with non return valves, the changeover regulator is easy to install. The changeover regulator is also fitted with an OPSO unit that will shut off the gas supply if the outlet pressure rises above 75 mbar.

The changeover automatically switches to a reserve cylinder when the pressure falls in the active supply cylinder. The indicator arrow turns red when the system has changed over and points to the empty cylinder. The indicator turns white when turned towards the new service cylinder.
