We have 3 series of expansion valve: S series, F series, ST(E) series
F series expansion valve
F series 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 refrigerating devices of small refrigeration capacity. The inlet connection has removable 100-mesh filter screen (only for SAE conic connection). The materials of the valve is made of bar and stainless steel (ODF connection materials are red copper). The valve can prevent rust and corrosion by the greatest extent. The connector is welded with valve body by high strength silver welding, capable of preventing leakage permanently. The sensing elements are sealed with advanced knife-tightening technology. It is both artistic and 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 connection
Length of standard capillary tube: 76cm (30inches)
S series expansion valve:
S series thermostatic expansion valve: The valve adopts brass bar, and is able to adjust flow capacity. Taking use of huge and flat stainless steel film and design of needle valve base, makes needle valve match correctly with the valve port and keeps good tightness between them. It can provide best performance for air conditioners and various refrigerating equipments. The welded tube and valve body both adopt high strength silver welding, so as to further prevent the leakage of valve body. The expansion valves of this series are the ones usually applied in air conditioners and various refrigerating devices
Sensing elements No.: 83 Knight-tight connection
Length of standard capillary tube: 152cm (60inches)
