EXPANSION VALVE ORIFICE 03. Orifice assemblies with filters, designed for use with either solder adapter product configurations or standard product configurations. The rated capacity is based on: Evaporating temperature te = +5°C for range N (–40 - 10°C) and te = –30°C for range B (–60 - –20°C) Condensing temperature tc = +32°C Refrigerant temperature ahead of valve tl = +28°C
