How to maintain a check valve

Check valves require little attention over long periods of time. Leakage may be caused by the presence of a tiny particle of foreign matter between the checking device (ball, cone, or poppet) and its seat. To remove the foreign matter, it is necessary to remove the valve from the aircraft and completely disassemble the valve. If no scratches are found on the valve seat or the checking device, wash all parts in clean hydraulic fluid of the same type as that used in the system.While the valve is disassembled, inspect thehousing and the checking device for evidence ofcorrosion. Replace the valve if there is corrosion orexcessive roughness. A slightly rough surface can be smoothed by buffing. A cone-type check valve may have a tendency to lean to one side, in which case the movable part may dig into the soft aluminum body of the housing and stick there.When installing a check valve, remember that the arrow marked on the housing must point in the direction of the flow of the fluid through the valve.Before removing a check valve from a line, it is good practice to mark the adjacent structure, indicating the direction in which the arrow points. Also, observe the following precaution during installation of check valves: Grip the wrench flats of the check valve at the end to which the connecting tubing is being installed.Do not grip the opposite end. This will prevent the possibility of distorting the valve body, causing the valve to leak.
