F series thermostatic expansion valveF series o Hangzhou SIKELAN thermostatic expansion valve: the valve body is made of brass bar and it exterior can adjust the flow rate of the valve, special for R-22 air conditioning systems and refrigeration devices of small refrigeration capacity.The inlet connection has removable 100-mesh filter screen (only for SAC conic connection). The materials of the valve is made of brass bar and stainless steel (ODF connection materials are red copper). The valve can prevent rust andcorrosion by the greatest extent. The sensing elements are sealed with advanced knife-tightening technology. It is both artisticand free of leakage. The valve needle is precisely aligned with valve port to avoid influencing the operation of the valve due to the large variation of pressure drop, which can offer an accurate control under the working condition of great variation. Sensing elements No.: 43 knife-tight connectionLength of standard capillary tube: 70cm (30inches)Model:FV-1 1/2FV-2FV-3FV-5
