Daikin-McQuay 300047539 4-Ton Thermal Expansion Valve (TXV) 1/2" X 1/2"

The Daikin-McQuay 300047539 Thermal Expansion-Valve is an essential component to be installed in HVAC systems which has a rating of 4 tons. The connection size of this TXV is 1/2” x 1/2” and it controls the amount of coolant that enters the evaporator to produce the right amount of coolness. It works based on signaling the refrigerant temperature coming out of the evaporator, a sensing bulb having a thermodynamic fluid that changes the opening of the valve depending on the superheat. This dynamic control assists in keeping the evaporator temperatures at a constant rate, thereby increasing system efficiency and optimum energy.
