4-way reverse valve for air conditioning, 1.5P-2P, copper, R410A/R22, optimal sealing

🔄 General Description: 4-way reverse valve for air conditioning — an essential replacement part for heat pump systems (1.5P–2P). Made of high-quality copper, it ensures smooth refrigerant flow between cooling and heating modes. Ideal for demanding DIYers: reliable with low pressure differential, leak-proof, quiet, and energy-efficient. ⚙️ Technical Specifications: Condition: 100% New; Material: Copper; Refrigerant Compatibility: R22, R407C, R404A, R410A; Fluid Temperature: -30°C to +120°C; Ambient Temperature: -25°C to +70°C; Max. Relative Humidity: ≤ 95% RH; Certifications: UL, VDE, PED; Type: Suitable for 1.5P–2P units. 🔧 Installation: Intuitive installation for professionals and experienced DIYers. No electrical connection required — only soldering on the refrigeration circuit. Protect the coil before disassembly. Use a damp cloth during soldering and favor silver or copper-phosphorus solder. Nitrogen is recommended to limit oxides. 🏡 Application: Works in reversible air conditioners, individual or central heat pumps. Allows instant switching between cooling and heating — optimal comfort all year round, without compromising on efficiency or quiet operation. ℹ️ Other information: Package contents: 1 x 4-way valve. Before installation, plug the 4 ports with plastic caps. Check that the internal slide is on the left. Avoid overheating the valve body during soldering — control the flame direction, no direct contact.
