Pressure Maintaining / Non Return Valve
The pressure maintaining / non return valve combination is
placed in the flow direction after the final filter housing.
Pressure Maintaining Valve
The pressure maintaining valve drains a large part of the wa-
ter content of the compressed air mechanically by ensuring
the minimum outlet pressure. This guarantees optimal drying
and purification of the breathing air.
After starting the compressor, the pressure inside the final filter
housing constantly increases. The pressure maintaining the valve
prevents the compressed air from blowing off (final pressure
gauge = 0 bar).
When the adjusted opening pressure is reached (150 and 180 bar), the purified compressed air
flows via pressure maintaining and non return valve to the filling valve.
The value of the opening pressure of the pressure maintaining valve can be read at the final pres-
sure gauge. When opening pressure is reached, the pressure gauge value increases within a few
seconds.
Adjust pressure maintaining valve see next page.
Non Return Valve
The non return valve which is placed after the pressure maintaining valve, prevents the purified bre-
athing air from flowing back into the filter housing / condensate drain valves.
After compressor stop, the indicated filling pressure remains constant, if the non return valve is
working correctly.
