• Features 1、Reliable operation below low stress difference, and it has low stress drop and inside leakage 2、The electromagnetic coil is product of thermosetting plastic, water resistance, lightning resistance and perfect insulation functionality 3、More energy‑saving, low temperature rise, low noise and good anti‑vibration performance 4、Excellent sealing performance, excessive calories efficiency, gentle weight, nice vibration resistance and environmental protection 5、It is used in warmth pump variety programs such as central, unit and room air conditioners to transform the refrigeration components and the heating components through means of switching the move course of the refrigerantSpecification Features:Reliable operation below low strain difference, and it has low pressure drop and inside leakage electromagnetic coil is manufactured from thermosetting plastic, water resistance, lightning resistance and excellent insulation performance energy-saving, low temperature rise, low noise and good anti-vibration functionality sealing performance, excessive energy efficiency, mild weight, good vibration resistance and environmental defense is utilized in heat pump variety methods comparable to central, unit and room air conditioners to transform the refrigeration method and the heating method through switching the move path of the refrigerant. Specification:Condition: Brand NewMaterial: CopperUse: From 1 to one hundred twenty ton of refrigeration, a variety of useApplicable Refrigerant: R22, R407C, R404A, R410A, and so on Medium temperature: -30℃~+120℃Applicable Ambient Temperature: -25℃~+70℃Relative humidity: 95% RH or lessCertification: UL, VDE, PED Package list:1 * Air Conditioning Four-way Valve Note:2. The coil of the concern valve ought to be removed before desoldering the four-way valve to bypass burning the coil during the welding process. Before desoldering the four-way valve, the four-way valve should be wrapped with a humid cloth and the four-way valve meeting needs to be welded. Pay attention to the route of the flame when welding, and don't enable the flame to heat the valve body. Immerse the four-way valve assembly in water for replacement. In order to regulate the relative attitude between the four-way valve meeting lines, a way of removing one after which welding one could be taken. When installing the four-way valve assembly, the four-way valve should be wrapped with a moist cloth, and the path of the welding flame ought to be noted, and the flame shouldn't be heated against the valve body. When replacing the four-way valve, to be able to make sure the welding superb of the copper pipe, silver-containing brazing filler metal should be used as lots as possible. If there is not any silver-containing brazing filler metal, copper-phosphorus brazing filler metal and fluxing agent can be used for welding. If possible, nitrogen filling defense needs to be taken during welding to reduce the formation of oxide skin. After the welding is completed, the oxide pores and skin contained in the four-way valve is purged with nitrogen. When cooling, care needs to be taken to bypass moisture List 1 * Air Conditioning Four-way Valve (Interface random)
