Description
Emerson Flow Control (Alco) 066662 Thermal Expansion Valve is an essential part used in HVAC systems for air conditioning and heat pump systems using R410A refrigerant. This valve holds a 3-ton capacity and controls the flow of refrigerant into the evaporator to enable better heat removing efficiency. It has an externally equalized design which makes it work better by allowing different pressures inside the system. The TXV works on a sensing bulb that contains a liquid which changes with temperature and controls the refrigerant flow to achieve the required superheat.
