4190002822 Expansion Valve

The 4190002822 expansion valve is a core refrigeration and pressure regulating component for the HVAC air conditioning system of heavy-duty trucks and construction machinery. As a key part of the refrigeration cycle, this expansion valve precisely controls refrigerant flow and reduces refrigerant pressure. It converts high-pressure liquid refrigerant into low-pressure gas, ensuring efficient heat exchange and stable cooling performance for the cab air conditioner. Adopting high-precision internal throttle structure and anti-corrosion alloy body, it features sensitive flow adjustment, stable refrigeration effect and excellent leak-proof performance. Manufactured strictly according to OEM dimensional and technical standards, the 4190002822 expansion valve achieves 100% interchangeability for direct replacement and routine air conditioning maintenance.
