Description
The Emerson Flow Control (Alco) 066658 3-1/2 to 5-Ton Thermal Expansion Valve (TXV) with R-22 is a refrigerant control component to manage, the flow of refrigerant into the evaporator coil according to cooling in HVAC systems. It works by detecting temperature and pressure variations at the evaporator inlet and adjusting the metering orifice to maintain the appropriate level of superheat for effective heat absorption. It is installed in air conditioners and heat pumps with R-22 refrigerant as part of the refrigeration control system which assists HVAC systems in balancing the flow of refrigerant assist in maintaining steady performance.
