CRO Armature repair

With CRO valves leakproof and can be dismantled for inspection and cleaning, they tend to replace if damaged. If the CRO may not open, close properly, or will not adjust, soldering or other foreign matter, probably delivered in the port. Sometimes you can move these materials by turning the adjustment nut with a running system. If CRO develops refrigerant leakage around the spring housing, it has probably overheated during installation or bellows failed due to severe compressor pulsations. In any case, this valve must be replaced.
