Reliable operation even at low pressure differentials, optimal sealing, and low noise. Perfect for demanding DIYers looking to repair or upgrade their refrigeration system with confidence. ⚙️ Technical Specifications: Material: High-purity copper; Compatible refrigerants: 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: 1.5P–2P (ready to install) Contents: 1 brand new 4-way valve 🔧 Installation Quick and intuitive installation — designed for professionals and experienced DIYers. No special tools required: simple disassembly, torch soldering with a moistened valve body cover. Use silver solder (or copper-phosphorus + flux) and, if possible, nitrogen to prevent oxides. 🔄 Use Allows instant switching between cooling and heating modes in air-to-air heat pumps. Meets the requirements of residential and commercial installations: optimal thermal comfort all year round, increased energy savings, and quiet operation. ℹ️ Other information Before handling: plug the 4 ports with plastic caps. Check the position of the internal spool (must be on the left). Remove the coil before soldering. Never directly heat the valve body. For a perfect angle of the fittings, use the "place-one-weld-one" method.
