One-way valves: It is mainly used for air-condition, refrigerating machine and so on refrigeration system. When the system is refrigeration, it is expedite in the same direction, on the contrary, it is throttled in reverse, so improve the ability of heatting machine and so on refrigeration system. When the compre-ssor stopped, it can prevent the refrigerating fluid to flow back and when heating, it can incr-ease the flow of freezing medium and raise heat efficiency.
