4190002822 Expansion Valve for SDLG WHEEL LOADER

Structural Composition:

Brass valve body, throttling main body, precision throttling orifice

External temperature sensor + capillary tube (attached to the evaporator outlet pipe)

Sealing diaphragm, adjusting spring, standard inlet and outlet connectors

Integrated mounting clips for direct installation into the evaporator housing

Material Advantages:

All-copper valve body is pressure-resistant and vibration-resistant, preventing leakage at high and low temperatures on construction sites

Capillary tube is resistant to bending and breakage, highly sensitive to temperature, and accurately regulates refrigerant flow

Sealing gasket is resistant to refrigerant corrosion, preventing refrigerant leakage

III. Core Functions (Core throttling element of the air conditioning refrigeration system)

Throttling and Pressure Reduction: High-pressure liquid refrigerant passes through a small valve orifice, reducing pressure and temperature, becoming a low-temperature, low-pressure gas-liquid mixture that is then sent to the evaporator. 4190002757; Automatic flow regulation: The temperature sensor collects the evaporator outlet temperature and automatically adjusts the valve opening to match different cooling loads; Compressor protection: Controls the refrigerant flow in the evaporator to prevent liquid refrigerant backflow from impacting the compressor (liquid slugging damage); Indispensable to the entire refrigeration cycle, installed inside the evaporator inlet.

IV. Complete 7-piece set of cooling and heating air conditioning
