Trane VAL4416 Thermal Expansion Valve (TXV) 500 PSI R-22 5 Ton

The Trane VAL4416 is a 5.7" long thermal expansion valve for accurate refrigerant control in R-22 air conditioning systems up to 5 tons. Made of robust brass, this valve can take pressures up to 500 PSI. The VAL4416 differs from electrically operated TXVs by using a thermal actuator. The evaporator coil temperature causes this actuator to expand or contract. When the temperature begins to rise the actuator then opens the valve allowing. At lower temperatures, refrigerant flow is limited by the valve. This exact management ensures efficient heat transfer from the air into the evaporator coil and also prevents flooding in the evaporator coil with extra refrigerant, reducing efficiency and harming the system.
