Note:
1. 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. 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.1. Before replacing the four-way valve. use a plastic plug to block the four nozzles to prevent impurities from entering the four-way valve. Before welding. check the position of the four-way valve slider inside the main valve body of the four-way valve. which should be on the left when normal. If in the middle or on the right. tap the valve body and knock the slider to the left.
2. 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.
3. 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.

• How to Install: 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.
• Excellent Performance: Air conditioning reversing valve is reliable operation under low pressure difference. and it has low pressure drop and internal leakage.more energy-saving. low temperature rise. low noise and good anti-vibration performance. light weight.and environmental protection.
• Perfect Sealing: The electromagnetic coil is made of thermosetting plastic. water resistance. lightning resistance and excellent insulation performance.excellent sealing performance. high energy efficiency.the coil of the priority valve must be removed before desoldering the four-way valve to avoid burning the coil during the welding process.
• Suitable Occasion: This air conditioning four way valve 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 flows path of the refrigerant.
• How to Use: 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.
