VAL8593 | 5/16x1/2 R410A 4Ton TXV | Trane

VAL8593 5/16x1/2 R410A 4Ton TXV Thermostatic Expansion Valve by Trane The VAL8593 is a thermostatic expansion valve (TXV) made by Trane. It is designed for use with 4-ton R410A refrigeration systems. The TXV controls the flow of refrigerant into the evaporator coil, ensuring that the coil is properly flooded for maximum heat transfer. The VAL8593 is a piston-type TXV, which means that it uses a piston to regulate the flow of refrigerant. The piston is moved by a diaphragm that is actuated by the pressure of the refrigerant in the evaporator coil. As the pressure in the evaporator coil increases, the diaphragm moves the piston to reduce the flow of refrigerant. As the pressure in the evaporator coil decreases, the diaphragm moves the piston to increase the flow of refrigerant. The VAL8593 is a reliable and efficient TXV that is essential for the proper operation of a refrigeration system. It is easy to install and maintain, and it provides years of trouble-free operation.
