Lennox 67K18 5/8 Suction Valve

The Lennox 67K18 5/8 Suction Valve is a crucial component in HVAC systems that controls the refrigerant flow. Typically crafted from durable brass to resist the high pressures and temperatures within refrigerant lines, this valve regulates the flow based on system pressure. It opens and closes to direct refrigerant towards the compressor, where it gets compressed and circulated throughout the system. By precisely controlling the refrigerant flow, the suction valve optimizes system performance and efficiency. In simpler terms, it ensures the refrigerant circulates within the AC system at the correct pressure, leading to efficient cooling. While the information you provided mentions a size of 3/4 Inch, it's important to clarify that the Lennox 67K18 is actually a 5/8 Inch suction valve. You might find resources online mentioning 3/4 Inch suction valves with similar part numbers. It's always best to double-check the part number with your specific HVAC unit before purchasing a replacement.
