BLR/DEV Hot Gas Dypass Expansion Valves
◆The Model BLR/DEV Discharge-bypass valve is used in the refrigerating compressor set,which is not equipped with energy unloading device, to realize the systematic energy regulation.
◆The Model BLR/DEV Discharge-bypass valve can be used as automatic expansion valve under fixed pressure to maintain the fixed evaporation pressure(temperature).
◆The Model BLR/DEV Discharge-bypass valve is capable to prevent the refrigeration compressor set from extract decreasing lower than the minimum value.
◆Connecting means include flare with thread and ODF copper pipe welding.
◆Suitable mediums are various kinds of Freon and hydrocaibon compounds.
◆Maximum working pressure:2.8Mpa.
