01WORK SAFETY PROTECTIVE EQUIPMENT
Precision Flow Control for Heat Pumps
Hidden within the complex network of pipes and coils, this valve acts as the critical switch that allows your climate control system to shift from cooling to heating. It is an essential component for maintaining comfort in diverse weather conditions.
Designed for heat pump type systems, this accessory manages the flow path of refrigerant with precision. It suits technicians and engineers working on central, unit or room air conditioning units who require reliable performance under varying pressure differences.
02MATERIALS
Robust Copper Construction
Crafted from copper, the valve body provides a sturdy foundation for handling refrigerant flows. The electromagnetic coil is encased in thermosetting plastic, which delivers excellent insulation performance alongside water and lightning resistance. This material combination ensures the component remains stable even when exposed to humid environments or electrical fluctuations during operation.
04SPECS
Wide Range Compatibility
This unit handles refrigeration loads from one to 120 tons, making it suitable for a broad spectrum of applications. It works with common refrigerants including R22, R407C, R404A and R410A. The operating range covers medium temperatures from -30°C to +120°C and ambient conditions from -25°C to +70°C, with tolerance for up to 95% relative humidity.
05PACKAGING
Compact Packaging Dimensions
The product arrives in a compact carton measuring 15 x 11 x 9 cm, weighing just 0.53 kg including the packaging. This lightweight presentation makes storage and transport straightforward for workshop inventories or on-site service kits. The small footprint reflects the efficient, light-weight nature of the valve itself, designed for easy integration into existing system layouts.

Reliable operation under low pressure difference, and it has low pressure drop and internal leakage.
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.
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.
The coil of the priority valve must be removed before desoldering the four-way valve to avoid burning the coil during the welding process.
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.
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.
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.
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.
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.8.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
