【Product Specifications】This 4-way heater control valve is designed for automotive air conditioning (climate control) systems, specifically regulating coolant flow through heater circuits. Suitable for hoses with an inner diameter of 5/8 inches (16 mm). Operating temperature: -20°F to 305°F (-29°C to 152°C); Working pressure: 232 PSI (1.6 MPa).
【Premium Materials】Crafted with CNC precision, this four-way heater core bypass valve features a smooth, burr-free surface. The coated knobs offer a comfortable grip. Made from high-quality solid brass with anti-corrosion plating, it delivers superior durability and a long lifespan. Resistant to rust, corrosion, and aging, it also withstands high temperatures without deformation.
【Single-Knob Dual-Mode】Forged from military-grade brass with 4-channel precision engineering, this valve delivers season-optimized performance with a single twist of the knob. Summer mode diverts coolant from the heater core to boost A/C efficiency, maintaining a refreshingly cool cabin; winter mode closes the flow path to concentrate heat distribution, achieving faster cabin warming with sustained comfort.
【Monolithic Design】Forged through high-pressure die-casting as a single unit, this integrated four-way connector eliminates screws while delivering leak-proof performance with advanced sealing technology. By maintaining optimal coolant levels in the reservoir and preventing engine overheating from fluid depletion, the unified structure enhances system reliability and simplifies installation.
【Quick-Connect Installation】Simply insert the hose and tighten the clamp—always ensure the cooling system is fully depressurized and cooled before installation. Secure connections with hose clamps to prevent leaks (included clamps must be properly torqued).
【Package Contents】1 x 4-way Heater core bypass valve, 4 x Heavy-duty German-style hose clamps (for automotive high-pressure connections), 1 x Phillips screwdriver (Note: Universal clamps fit both 5/8" and 3/4" valves).
