The air supply can only be done via port 1 Ensure that the downstream air consumption will not cause a pressure drop which could result in the pressure falling below the minimum operating values. If the pressure inside the valve falls below 2 bars , the valve might shut off. Atex certification (II 2GD o II 3GD) on request Electric shut-off valve
