VAL7558
The Trane VAL7558 5-Ton Thermal Expansion Valve (TXV) is Designed to optimize refrigerant flow in air conditioning and refrigeration systems. It uses a capillary tube of 36 inches in length to control the flow of the liquid refrigerant according to the evaporating temperature. This helps in achieving the better performance of the system and at the same time, it will have the right superheat. It can handle R-22, R-407C, and R-410A refrigerants and is suitable for several commercial and industrial uses. This valve helps to optimize system performance, use less energy, and increase reliability through proper measurement of refrigerant flow.
