The electromagnetic coil is made of thermosetting plastic water resistance lightning resistance and excellent insulation performance. More energy-saving low temperature rise low noise and good anti-vibration performance. Excellent sealing performance high energy efficiency light weight good vibration resistance and environmental protection. It is used in heat pump type systems such as central unit and room air conditioners to convert the refrigeration system and the heating system by switching the flow path of the refrigerant. Specification:Condition: NewMaterial: CopperUse: From 1 to 120 ton of refrigeration a wide range of useApplicable Refrigerant: R22 R407C R404A R410A etc.Applicable Medium temperature: -30~+120Applicable Ambient Temperature: -25~+70Relative humidity: 95% RH or lessCertification: UL VDE PEDPackage list:1 * Air Conditioning Four-way ValveNote:2. The coil of the priority valve must be removed before desoldering the four-way valve to avoid burning the coil during the welding process.3. Before desoldering the four-way valve the four-way valve must be wrapped with a damp cloth and the four-way valve assembly should be welded. Pay attention to the direction of the flame when welding and do not allow the flame to heat the valve body.4. Immerse the four-way valve assembly in water for replacement. In order to control the relative angle between the four-way valve assembly lines a method of removing one and then welding one can be taken.5. When installing the four-way valve assembly the four-way valve must be wrapped with a damp cloth and the direction of the welding flame should be noted and the flame should not be heated against the valve body.6. When replacing the four-way valve in order to ensure the welding quality of the copper pipe silver-containing brazing filler metal should be used as much as possible. If there is no silver-containing brazing filler metal copper-phosphorus brazing filler metal and fluxing agent can be used for welding.7. If possible nitrogen filling protection should be taken during welding to reduce the formation of oxide skin. After the welding is completed the oxide skin inside the four-way valve is purged with nitrogen. When cooling care should be taken to avoid moisture.
