4-way reverse valve for air conditioning – copper fittings, compatible with R22/R410A, 1P

❄️ General Description This 4-way diverter valve for air conditioning is the key component of reversible heat pump systems. Designed for professionals and experienced DIYers, it allows for easy switching between cooling and heating modes by reversing the direction of the refrigerant. Robust, quiet, and energy-efficient, it guarantees optimal reliability even at low pressure differentials. ⚙️ Technical Specifications Material: High-purity copper Compatible fluorocarbons: R22, R407C, R404A, R410A Fluid temperature range: -30°C to +120°C Operating ambient temperature: -25°C to +70°C Max. relative humidity : ≤ 95% RH Certifications: UL, VDE, PED Type: 1P (other versions available upon request) Package Contents: 1 x 4-way diverter valve (random connections) 🔧 Installation Installation is quick and intuitive for any qualified technician. No special tools are required: simple disassembly, torch welding with protection by a damp cloth and nitrogen recommended. Positioning the internal spool (left before welding) and pre-removing the solenoid coil ensure error-free installation. 🏡 Use Ideal for monobloc, split, or central air conditioners, this 4-way valve transforms your system into a smart heating/cooling system. You enjoy perfect thermal comfort all year round — without changing equipment, without compromising on performance or quiet operation. ℹ️ Other Information Designed for a long service life: reinforced sealing, high vibration resistance, and low heat rise. The thermoset plastic coil offers excellent resistance to moisture and voltage surges. For use exclusively in professional installations that comply with European refrigeration standards.
