Type
Orifice Tubes
Four Seasons' expansion devices are specifically calibrated to provide proper flow to the evaporator as well as restricting or modulating high pressure liquid causing a pressure drop to lower the refrigerant temperature. They also provide optimum cabin comfort for both the driver and passengers.
Features & Benefits
Separates high side from low side
Regulates flow of liquid refrigerant into evaporator (Creates restriction)
Refrigerant boils (evaporates) upon entering low pressure area in evaporator
Refrigerant flows through fixed diameter tube- Diameter set by system design
Flow rate determined by pressure drop across orifice & tube diameter
Performance optimized at highway speeds
Orifice Tubes are built application specific per OEM size and color
Benefits of a Premium Variable Orifice Valve (VOV)
A Premium Variable Orifice Valve (VOV) is designed to change outputs based on different operating conditions. This significantly improves A/C performance at low speeds and idle, by allowing more refrigerant to flow.
