The Sporlan Controls 129523 Thermostatic Expansion Valve (TXV) is a flow metering component that regulates the refrigerant supply entering the evaporator to maintain proper cooling balance. It uses temperature and pressure changes within the circuit to adjust valve movement and control the amount of refrigerant delivered in HVAC systems. The 1.5-ton capacity identifies its intended cooling range while the R22 specification define the compatible refrigerant type. The 1/2" inlet and 5/8" ODF outlet connections provide the required tubing interfaces for integration. This valve supports effective heat transfer, controlled flow adjustment and steady cooling operation.
