Application :
1.Help starting compressor under low temperature 
. The valve is used for condensing unit system .which help start compressor available in  low temperature .Because in low temperature .the high pressure terminal of compressor lock of high pressure .Then the pressure difference is locked between high pressure terminal and low pressure terminal . the compressor can not be started for this problem . And the compressor will be damaged .The valve helps to provide enough pressure difference for starting compressor .
2.For checking and turn off in cooling system .
When compressor is closed ,it can cut the connection between compressor and discharge pipe ,which avoid of high pressure gas back flow.
