Description
The Copeland Comfort Control (Alco) 806818 Expansion Valve is a high-capacity refrigerant control part. that regulates liquid flow into the evaporator based on load demand in HVAC systems. It is rated for 25-ton applications and features a Maximum Operating Pressure (MOP) of 175 PSI, allowing controlled refrigerant delivery under varying load conditions. This valve is part of the TX7 series which uses a balanced port design to maintain stable superheat and reliable performance across a wide operating range. It is typically installed at the evaporator inlet in large commercial or industrial equipment, where precise refrigerant control is required. Its role is to ensure accurate refrigerant feed supporting efficient cooling and consistent system operation.
