Used in the refrigerating compressor set(without energy unloading device) to realize the systematic energy regulation.
• Can be used as autometic expansion valve under fixed pressure to maintain the fixed evaporation pressure(temperature).
• Can prevent the refrigerating compressor set from extract pressure decreasing lower than the minimum value.
• Connecting means include flare with thread and ODF copper pipe welding.
• Maximum working pressure: 2.8 MPa.
