Description
The Trane VAL07632 2.50-Ton Expansion Valve is a refrigerant metering fixture that regulates the flow of R22 into the evaporator based on system demand to maintain proper superheat control and efficient cooling. It operates through a thermostatic sensing mechanism that adjusts internal valve opening according to temperature and pressure changes, ensuring precise refrigerant distribution. HVAC systems depend on this regulation to achieve stable coil performance and balanced cooling output during operation. It is positioned at the evaporator inlet line with 0.38″ ODF connections, it forms part of the refrigeration circuit, supporting consistent heat transfer, preventing liquid floodback, and improving overall system stability.
