The Copeland Comfort Control (Alco) 091049 8-Ton Thermostatic Expansion Valve 5/8″ x 7/8″ ODF with 5′ capillary is a refrigerant metering tool used to regulate liquid refrigerant flow into the evaporator coil in HVAC systems. It works by sensing evaporator temperature and pressure through its capillary tube and adjusting valve opening to maintain proper superheat for efficient heat transfer. It is used in large air conditioning and refrigeration systems operating with R410A refrigerant. Its precise flow control, improved energy efficiency, and consistent compressor protection help ensure stable cooling performance in systems.
