Втулка клапана теплового расширения Caterpillar 5758278

The Thermal Expansion Valve Sleeve functions as a guiding and supporting component for the thermal expansion valve within the refrigeration and air-conditioning system. It ensures accurate movement of the valve piston and needle, allowing proper control of refrigerant flow between high-pressure and low-pressure zones. It maintains a sealed and aligned passage, aiding in consistent refrigerant expansion, which directly influences cooling efficiency and system performance.Attributes:• Maintains reliable sealing under varying temperature gradients.• Ensures responsive modulation of refrigerant as system demand changes.• Ensures accurate refrigerant expansion within the evaporator circuit.Applications: The Thermal Expansion Valve Sleeve is used in refrigeration and air-conditioning systems to guide valve operation and regulate refrigerant flow for efficient cooling performance.
