Cek leakage in evaporator
I have new an evaporator using TEV externally equallizer intalled in this unit. I want to test leakage using gas with high pressure about 10 bar and using detergent water. I will fill the gas from inlet TEV. Is it permitted ? Is TEV valve in open orifice or closed orifice in the ambient temperature. I buy TEV from danfoss type TE N 2. I'm worried the gas can not pass through TEV and I can not check leakage in the evaporator side and pipe externally equalizer that is connected in the out of evaporator tube because there is no pressure inside tube. Please need your advice

Hello Cewek
The gas will pass through the TEV ok but it will be a little slow.
TE2 N is for r134a so why 10 bar test pressure for leakage. Please check manufacturer recommendations for maximum.
here is a link for the TE2
