Description
The Copeland Comfort Control (Alco) 064219 10-Ton Thermal Expansion Valve R404A 5/8″ X 7/8″ ODF Angle is a thermostatic metering equipment used to regulate refrigerant flow into the evaporator based on system load conditions. It maintains controlled superheat by adjusting flow to ensure complete vaporization inside the coil and stable compressor protection. Installed in air conditioning and heat pump systems, it prevents liquid vapor return, supports efficient heat exchange between indoor and outdoor units, and ensures consistent cooling performance. It is applied in commercial and residential heating and cooling systems where precise expansion control and stable operation are required.
