Pressure Line Filter Circuit

This circuit protects the directional and other control valves in the line. Its filtration rate ranges from about 10^m (solenoid/proportional valve) to 3 ^m (servo valve, etc.).

This circuit has an objective similar to that of Fig. 15.16, but it filters out contaminants from the cylinder. It is better to filter out contaminants from only one direction with the anti-reverse-flow valve.
