New, large pressure regulator for use on valve terminals, whereby pressure can be precisely set manually. Pressure can be conveniently read from the front or from above via the swivelling pressure gauge. Compressed air consumption is reduced by up to 50%, since the pressure set is maintained constant irrespective of air consumption. The economic benefits are considerable, whilst components are subject to only minimal wear and tear. Configuration in the Festo Corporate Design ensures transparency: the pressure regulator and valve terminal are ideally harmonised and the blue-coloured control elements are easily identifiable.
