Valve Orifice in Thermal Expansion Valves
Tiny valve orifice controls massive cooling power with precision and risk
8 Feb 2026
0
How does the valve orifice in a thermal expansion valve balance system efficiency and compressor safety?
By directly controlling the evaporator temperature to a precise value regardless of load changes.
By allowing unrestricted refrigerant flow to maximize cooling capacity at all times.
By regulating refrigerant flow to maintain steady superheat, preventing liquid refrigerant from reaching the compressor while ensuring adequate cooling.
